Understanding Achilles Tendon Pain
Why The Back Of Your Ankle May Hurt During Walking, Running, Or Exercise
You get out of bed and the first few steps feel unusually stiff.
The back of your ankle aches as you walk.
Maybe the discomfort improves once you get moving, only to return after a run, long walk, workout, or busy day on your feet.
One possible cause is Achilles tendinopathy, a condition involving irritation and changes within the Achilles tendon.
The Achilles tendon is the large tendon connecting your calf muscles to your heel bone. It plays an important role every time you:
- Walk
- Run
- Climb stairs
- Jump
- Push off your foot
- Stand on your toes
Achilles symptoms often develop gradually after repetitive loading or a sudden increase in activity.
However, a sudden pop, severe pain, immediate weakness, or difficulty pushing off the foot can suggest a more significant Achilles injury and should not be treated like ordinary tendon soreness.
At Z-2-H Family Med & Urgent Care, our providers can evaluate appropriate non-emergency ankle, heel, and musculoskeletal concerns and help determine whether Achilles tendon irritation or another condition may be contributing.
What Is The Achilles Tendon?
The Achilles tendon is one of the strongest tendons in the human body.
It connects the calf muscles to the calcaneus, or heel bone.
When your calf muscles contract, the Achilles tendon helps pull the heel upward.
This allows you to:
- Push off while walking
- Run
- Jump
- Stand on your toes
- Climb stairs
Because the tendon handles substantial forces, sudden changes in physical activity can sometimes overload it.
Quick Answer: What Does Achilles Tendon Pain Feel Like?
Achilles tendinopathy commonly causes aching, tenderness, or stiffness along the back of the ankle above the heel.
Symptoms may be worse:
- First thing in the morning
- During the first few steps after resting
- After running
- After long walks
- While climbing stairs
- During jumping
- After suddenly increasing exercise
The tendon may also feel slightly thickened or tender when pressed.
Where Does Achilles Tendon Pain Occur?
Pain usually occurs along the back of the ankle.
There are two common areas.
Mid-Portion Achilles Pain
Usually develops several centimeters above the heel bone.
Insertional Achilles Pain
Occurs closer to where the tendon attaches directly to the heel.
The location can affect which activities and treatments are most appropriate.
Why Is My Achilles Stiff In The Morning?
Morning stiffness is a common complaint with Achilles tendinopathy.
After several hours of rest, the tendon may feel:
- Tight
- Achy
- Stiff
- Difficult to move initially
The first few steps may be uncomfortable.
Some people notice that symptoms improve somewhat after moving around.
This pattern does not automatically confirm Achilles tendinopathy, but it is a common clue.
Why Does It Hurt When I First Start Walking?
The tendon goes from being relatively unloaded during rest to suddenly helping push the body forward.
If the Achilles is irritated, those first movements may be uncomfortable.
Symptoms may improve after several minutes as the tendon warms up.
However, pain that improves during activity does not necessarily mean the tendon is ready for unlimited exercise.
Can Achilles Pain Get Worse After Exercise?
Yes.
Some people feel relatively comfortable during exercise but experience increased pain:
- Later that evening
- The next morning
- After sitting for a while
This delayed response can be useful when deciding whether an activity level was too aggressive.
What Causes Achilles Tendon Pain?
Achilles tendinopathy often develops when the tendon is exposed to more load than it is prepared to tolerate.
Possible contributors include:
- Sudden increases in running
- Increasing exercise frequency
- Adding hills
- Sprinting
- Jumping
- Returning after a long break
- Increasing workout intensity too quickly
- Repetitive work or activity
- Certain footwear changes
There may not be one single triggering event.
Can Running Cause Achilles Tendonitis?
Running can contribute to Achilles symptoms, particularly when training changes quickly.
Examples include:
- Suddenly doubling mileage
- Adding speed work
- Running steep hills
- Running more days per week
- Returning to running after months off
Running itself does not automatically damage the Achilles tendon.
The issue is often how quickly the workload changes.
What Is Achilles Tendinopathy?
The term Achilles tendinopathy is often preferred for persistent tendon pain.
It describes changes within the tendon associated with repeated loading and reduced ability to tolerate stress.
Although people often say Achilles tendonitis, long-standing symptoms may involve more than simple inflammation.
That distinction matters because recovery often requires gradual rehabilitation, not just reducing inflammation.
Is Achilles Tendonitis The Same As Achilles Tendinopathy?
The terms are often used interchangeably in everyday conversation.
Technically:
Tendonitis
Suggests primarily inflammation.
Tendinopathy
Is a broader term that includes persistent tendon pain and structural changes.
For patients, the practical message is similar:
Persistent Achilles pain should be managed according to the actual severity and underlying problem rather than assuming it is simply temporary inflammation.
Can Walking Too Much Irritate The Achilles?
Yes.
A sudden increase in walking can overload the tendon.
For example:
NORMAL WEEK: 3,000–5,000 STEPS/DAY
then suddenly:
VACATION: 15,000–20,000 STEPS/DAY
may be enough to trigger symptoms in someone whose tendon is not accustomed to that workload.
Can Hiking Cause Achilles Pain?
Yes.
Hiking may increase stress on the Achilles because of:
- Hills
- Uneven terrain
- Longer distances
- Different footwear
- Carrying additional weight
Uphill walking in particular increases the demand on the calf and Achilles tendon.
Can Jumping Cause Achilles Pain?
Jumping places high forces through the Achilles.
Activities that may contribute include:
- Basketball
- Volleyball
- Plyometrics
- Jump rope
- Cross-training workouts
- Dance
Sudden increases in jumping volume may provoke symptoms.
Can Weightlifting Affect The Achilles?
Yes.
Exercises involving significant calf or ankle loading may aggravate an already irritated tendon.
Examples include:
- Calf raises
- Lunges
- Squats
- Sled pushes
- Olympic lifting
- Explosive movements
The issue is not necessarily the exercise itself, but whether the tendon can currently tolerate the load.
Can Sports Cause Achilles Tendon Problems?
Yes.
Sports involving repeated:
- Sprinting
- Jumping
- Accelerating
- Cutting
- Pushing off
can place substantial stress on the tendon.
Common examples include:
- Basketball
- Soccer
- Football
- Tennis
- Track
- Volleyball
Can You Get Achilles Pain Without Being An Athlete?
Absolutely.
Achilles pain can also affect:
- Walkers
- Hikers
- Workers on their feet
- People beginning a new exercise program
- Adults who suddenly become more active
You do not need to be a runner or competitive athlete to develop tendon symptoms.
Can Standing All Day Make It Worse?
Prolonged standing may aggravate symptoms, particularly in jobs where people are constantly:
- Walking
- Climbing stairs
- Carrying items
- Moving between locations
Work demands should be considered when planning recovery.
Can A Change In Shoes Trigger Achilles Pain?
Potentially.
A sudden footwear change can alter how the ankle and tendon are loaded.
Examples may include switching between:
- High-heeled shoes and flat shoes
- Heavily cushioned shoes and minimalist shoes
- Different running shoes
- Work boots and athletic shoes
Footwear is rarely the only factor, but sudden changes may contribute.
Does A Flat Shoe Stretch The Achilles More?
Lower-heeled footwear may place the ankle in a position that increases tension through the Achilles compared with shoes that have more heel elevation.
This does not mean flat shoes are inherently harmful.
A sudden transition can simply change what the tendon is being asked to tolerate.
What Are The Symptoms Of Achilles Tendinopathy?
Common symptoms may include:
- Pain above the heel
- Tenderness
- Morning stiffness
- Pain when walking
- Pain with running
- Pain when climbing stairs
- Pain during jumping
- Mild tendon thickening
- Discomfort during calf raises
Symptoms often develop gradually.
Does Achilles Tendinopathy Cause Swelling?
Mild swelling or thickening can occur.
However, significant swelling after a sudden injury deserves additional attention.
A severely swollen ankle may indicate:
- Tendon injury
- Sprain
- Fracture
- Other conditions
Can The Achilles Tendon Feel Thick?
Yes.
Long-standing tendinopathy may cause part of the tendon to feel thicker than the other side.
This does not necessarily mean it is about to rupture.
A provider can evaluate whether the thickening appears consistent with tendinopathy or another condition.
Does Achilles Tendon Pain Cause Numbness?
Numbness and tingling are not classic symptoms of Achilles tendinopathy.
If you experience:
- Numbness
- Tingling
- Burning
- Weakness extending through the foot
a nerve-related problem or another condition may need to be considered.
Achilles Tendon Pain Vs. Plantar Fasciitis
These commonly involve different locations.
Achilles Tendon Pain
Usually affects the:
BACK OF ANKLE / ABOVE HEEL
Plantar Fasciitis
Typically causes pain along the:
BOTTOM OF THE HEEL
Both can be worse during the first steps after rest, which sometimes causes confusion.
Achilles Pain Vs. Ankle Sprain
An ankle sprain commonly follows a twisting injury.
Symptoms often include:
- Swelling
- Bruising
- Pain around the ankle ligaments
- Difficulty bearing weight
Achilles tendinopathy more commonly develops gradually along the back of the ankle.
Achilles Pain Vs. Calf Strain
A calf strain usually involves injury to muscle tissue higher in the leg.
It may develop after:
- Sprinting
- Jumping
- Sudden acceleration
A person may notice sudden pain within the calf rather than directly along the tendon.
Achilles Pain Vs. Heel Bursitis
A bursa near the heel can also become irritated.
This may produce pain near the back of the heel and can overlap with insertional Achilles symptoms.
A medical examination can help determine which structure is involved.
Achilles Pain Vs. Achilles Rupture
This distinction is extremely important.
Achilles Tendinopathy
Usually develops gradually.
Symptoms may include:
- Aching
- Morning stiffness
- Tenderness
- Pain after exercise
Achilles Rupture
Often occurs suddenly.
Possible symptoms include:
- A sudden pop
- Feeling as though someone kicked the back of the ankle
- Immediate pain
- Sudden weakness
- Difficulty pushing off
- Difficulty walking normally
- Difficulty standing on the toes
A suspected rupture needs prompt medical evaluation.
What Does An Achilles Rupture Feel Like?
Many people describe:
- A loud pop
- A snapping sensation
- Sudden sharp pain
- Feeling struck from behind
Some people turn around because they believe someone kicked them.
There may also be swelling and difficulty using the leg normally.
Can You Still Walk With A Torn Achilles?
Sometimes.
This is important because being able to walk does not completely rule out an Achilles rupture.
Walking may be abnormal and pushing off can be difficult.
If there was:
SUDDEN POP + PAIN + WEAKNESS
seek prompt evaluation even if you can still take steps.
Why Is Standing On Your Toes Important?
The Achilles helps lift the heel.
A person with significant Achilles injury may struggle to:
- Perform a calf raise
- Push off
- Stand on the toes
However, do not repeatedly test a severely injured ankle at home if rupture is suspected.
What Is The Thompson Test?
The Thompson test is a clinical examination maneuver used when an Achilles rupture is suspected.
A healthcare professional squeezes the calf and observes whether the foot moves appropriately.
This is one piece of the evaluation.
It should not replace medical assessment when symptoms suggest a rupture.
How Is Achilles Tendinopathy Diagnosed?
Diagnosis usually begins with your symptoms and physical examination.
Your provider may ask:
- Where is the pain?
- When did it start?
- Is it worse in the morning?
- Did you increase exercise?
- Are you running?
- Did you hear or feel a pop?
- Can you walk normally?
- Was there an injury?
- Is the ankle swollen?
The answers help distinguish gradual tendon overload from acute injury.
What Happens During The Exam?
A provider may evaluate:
- Tendon tenderness
- Swelling
- Thickness
- Ankle movement
- Calf strength
- Walking
- Ability to push off
- Other areas of the foot and ankle
Additional testing may be recommended when necessary.
Do You Need An X-Ray?
An X-ray does not directly show the Achilles tendon well.
It may still be useful when a provider wants to evaluate for:
- Bone injury
- Heel abnormalities
- Arthritis
- Calcification
Not everyone with Achilles pain needs an X-ray.
Does Ultrasound Show The Achilles Tendon?
Yes.
Musculoskeletal ultrasound can sometimes show:
- Tendon thickness
- Tendon structure
- Tears
Whether ultrasound is needed depends on the clinical situation.
Do You Need An MRI?
MRI may be considered for:
- Suspected significant tears
- Unclear diagnosis
- Persistent symptoms
- Treatment planning in selected cases
It is not automatically necessary for routine tendinopathy.
How Is Achilles Tendon Pain Treated?
Treatment depends on:
- Severity
- Duration
- Activity level
- Location
- Whether a tear is present
For uncomplicated tendinopathy, management may include:
- Activity modification
- Temporary reduction of aggravating exercise
- Gradual tendon loading
- Strengthening
- Appropriate footwear adjustments
- Comfort measures
- Medication when medically appropriate
Persistent or severe symptoms may require referral.
Should You Completely Rest?
Not necessarily.
Long periods of complete rest can reduce the tendon’s ability to tolerate load.
Instead, many cases benefit from relative rest.
That means reducing activities that significantly worsen symptoms while maintaining comfortable activity.
For example:
RUNNING HURTS → TEMPORARILY REDUCE RUNNING
does not necessarily mean:
STOP ALL MOVEMENT
Should You Keep Running Through Achilles Pain?
Repeatedly running through worsening pain may prolong the problem.
A useful approach is to monitor:
- Pain during activity
- Pain afterward
- Symptoms the next morning
If your Achilles is significantly worse the following day, the previous workload may have been too much.
Can Walking Be Part Of Recovery?
Often, yes, if walking is tolerable.
You may need to temporarily reduce:
- Distance
- Hills
- Pace
The appropriate amount depends on symptoms.
Can Ice Help?
Cold therapy may provide temporary comfort after activity.
If using ice:
- Wrap it in cloth
- Avoid placing ice directly on the skin
- Limit application time
Ice may help soreness but does not rebuild tendon capacity.
Can Heat Help?
Warmth may feel helpful for morning stiffness in some people.
Gentle movement after warming up may also feel more comfortable.
Avoid excessive heat that could burn the skin.
Can Anti-Inflammatory Medication Help?
NSAIDs may provide temporary pain relief for some patients.
However, they are not appropriate for everyone.
Additional caution may be needed with:
- Kidney disease
- Stomach ulcers
- Bleeding risk
- Certain heart conditions
- Pregnancy
- Medication interactions
Ask a healthcare professional or pharmacist if uncertain.
Is Stretching Good For Achilles Pain?
It depends on the location and severity.
Gentle calf stretching may be appropriate for some people.
However, aggressively stretching an irritated tendon may worsen symptoms.
Insertional Achilles pain near the heel attachment may also respond differently to deep stretching than mid-tendon pain.
Do not force painful stretches.
What About Calf Raises?
Calf strengthening is commonly included in Achilles rehabilitation.
Exercises may eventually include:
- Double-leg calf raises
- Single-leg calf raises
- Slow controlled lowering
- Progressive resistance
The difficulty should increase gradually.
What Are Eccentric Achilles Exercises?
Eccentric exercises involve the muscle-tendon unit lengthening while under load.
Heel-lowering exercises are a well-known example.
These may be appropriate for certain types of Achilles tendinopathy, but they are not automatically the best starting point for every patient.
Exercise selection depends on:
- Pain location
- Severity
- Strength
- Tendon tolerance
What Is Progressive Tendon Loading?
The Achilles needs to tolerate force in order to function normally.
Rehabilitation often gradually progresses from easier to harder activities.
For example:
BASIC CALF STRENGTH → HEAVIER STRENGTH → FASTER MOVEMENTS → RUNNING/JUMPING
The progression should be based on symptoms and function.
Why Isn't Rest Alone Enough?
Rest can reduce symptoms temporarily.
But if you return from complete rest directly to your previous workload, the tendon may still be unprepared.
That can create a cycle:
PAIN → COMPLETE REST → FEEL BETTER → FULL ACTIVITY → PAIN RETURNS
Gradual rehabilitation helps rebuild tolerance.
Can A Heel Lift Help?
A temporary heel lift may reduce Achilles strain in selected cases by slightly decreasing tension through the tendon.
It is not necessary for everyone.
A provider can help determine whether it is appropriate.
What Shoes Are Best For Achilles Pain?
There is no single perfect shoe.
Look for footwear that:
- Fits comfortably
- Does not rub the painful tendon
- Provides appropriate support for the activity
- Does not create a sudden dramatic change from what you normally wear
Avoid choosing footwear based solely on marketing claims.
Should You Walk Barefoot?
Some people notice more Achilles discomfort when walking barefoot because there is no heel elevation.
Others feel fine.
If barefoot walking clearly worsens symptoms, temporarily limiting it may help.
Can A Boot Be Used?
A walking boot may sometimes be used for severe symptoms or certain injuries.
However, prolonged immobilization can have disadvantages and is not necessary for every case of tendinopathy.
A healthcare professional should determine when immobilization is appropriate.
Are Steroid Injections Used In The Achilles?
Steroid injections around the Achilles require particular caution.
Certain injections near the tendon may carry risks, including possible tendon weakening.
Injection decisions should be made by an appropriate healthcare professional familiar with Achilles disorders.
Does Achilles Tendinopathy Need Surgery?
Most uncomplicated cases do not initially require surgery.
Surgical evaluation may be considered for selected patients with persistent symptoms that have not improved despite an appropriate course of conservative care.
A confirmed rupture is a different situation and may require orthopedic evaluation.
How Long Does Achilles Tendinopathy Take To Heal?
Tendon recovery often takes time.
Some cases may improve over several weeks.
Persistent tendinopathy may require several months of progressive rehabilitation.
Factors affecting recovery include:
- Duration of symptoms
- Severity
- Activity demands
- Strength
- Consistency with rehabilitation
- Continued overload
Can Achilles Pain Come Back?
Yes.
Recurrence can occur if training increases faster than the tendon can tolerate.
A gradual return to:
- Running
- Sprinting
- Jumping
- Heavy calf work
can reduce the risk of re-aggravation.
How Can You Help Prevent Achilles Tendon Pain?
Helpful strategies may include:
- Increase exercise gradually
- Avoid sudden mileage jumps
- Add hills gradually
- Strengthen the calves
- Include recovery days
- Warm up before demanding activity
- Address pain early
- Avoid sudden major footwear or training changes
No prevention strategy eliminates every injury.
What Is The “Too Much, Too Fast” Problem?
A common pattern looks like:
NORMAL TRAINING → SUDDEN LARGE INCREASE → TENDON PAIN
Examples include increasing:
- Distance
- Speed
- Hills
- Frequency
all at once.
A more gradual progression allows the tendon time to adapt.
Can Teen Athletes Get Achilles Pain?
Yes.
Teenagers can develop Achilles and other heel-related symptoms.
However, heel pain in growing children and adolescents may also have different causes.
Persistent pediatric heel pain deserves evaluation rather than automatically being labeled Achilles tendonitis.
What About Older Adults?
Achilles tendinopathy can also affect middle-aged and older adults.
Someone does not have to participate in sports.
Routine activities such as:
- Walking
- Yard work
- Travel
- New exercise programs
can trigger symptoms after a sudden workload change.
Are Certain Medications Linked With Achilles Problems?
Certain medications have been associated with increased risk of tendon injury in some patients.
One notable group is fluoroquinolone antibiotics.
Do not stop a prescribed medication without medical guidance.
If significant new tendon pain develops while taking a medication known to affect tendons, contact an appropriate healthcare professional.
When Should You Schedule An Evaluation?
Consider having Achilles pain evaluated when:
- Pain persists
- Morning stiffness keeps returning
- Walking becomes uncomfortable
- Running is repeatedly limited
- The tendon is swollen or thickened
- Symptoms aren't improving
- Pain keeps returning
- You aren't sure whether you have tendonitis or another injury
Earlier assessment may help identify activity changes that are prolonging symptoms.
When Does Achilles Pain Need Prompt Medical Attention?
Seek prompt medical evaluation for:
- A sudden pop
- Severe pain after an injury
- Immediate weakness
- Difficulty pushing off the foot
- Difficulty walking normally
- Significant swelling
- Inability to stand on the toes
- Visible deformity or gap in the tendon area
These symptoms may indicate an Achilles tear or rupture.
What If The Ankle Is Red, Hot, And Swollen?
Significant:
- Redness
- Warmth
- Swelling
particularly with fever or feeling ill, may indicate another problem requiring medical evaluation.
Routine Achilles tendinopathy does not usually cause a severely red, hot ankle with systemic illness.
What To Expect During Your Visit
For appropriate non-emergency Achilles or ankle symptoms, your provider may:
- Ask when the pain began
- Identify the exact pain location
- Review recent exercise changes
- Ask about running or sports
- Ask whether there was a pop
- Examine the tendon
- Check ankle movement
- Evaluate calf strength
- Assess walking
- Determine whether imaging is appropriate
- Recommend treatment or referral
The goal is to determine whether symptoms represent gradual tendon overload, another ankle problem, or a more significant injury.

Frequently Asked Questions
What Does Achilles Tendon Pain Feel Like?
Achilles tendinopathy commonly causes aching, tenderness, or stiffness along the back of the ankle above the heel, particularly during walking, running, or the first few steps after rest.
Why Is My Achilles Stiff In The Morning?
Morning stiffness can occur because an irritated Achilles tendon may feel less flexible after several hours of rest.
Where Does Achilles Tendonitis Hurt?
Pain may occur several centimeters above the heel or directly where the tendon attaches to the heel bone.
Can I Walk With Achilles Tendonitis?
Many people can continue tolerable walking, although distance, speed, and hills may need to be temporarily reduced.
Should I Stop Running?
Not always, but running may need to be reduced or temporarily paused if it significantly worsens symptoms during or after activity.
Can Achilles Tendonitis Heal On Its Own?
Mild symptoms may improve with appropriate load modification, but persistent tendinopathy often benefits from progressive strengthening and rehabilitation.
Is Stretching Good For Achilles Pain?
Gentle stretching may help selected patients, but aggressive stretching can aggravate symptoms and may not be appropriate for every type of Achilles pain.
How Do I Know If I Tore My Achilles?
A sudden pop, sharp pain, immediate weakness, difficulty pushing off, or inability to stand on the toes can suggest a significant tear or rupture and warrants prompt medical evaluation.
Can You Walk With A Ruptured Achilles?
Sometimes, which means being able to walk does not completely rule out rupture.
How Long Does Achilles Tendinopathy Last?
Recovery varies. Some cases improve within weeks, while persistent tendon problems may require months of gradual rehabilitation.
Can Shoes Cause Achilles Pain?
Sudden changes in footwear may change tendon loading and aggravate symptoms in some people, but shoes are rarely the only factor.
When Should Achilles Pain Be Evaluated?
Consider evaluation when symptoms persist, repeatedly limit walking or exercise, keep returning, or are accompanied by significant swelling or weakness.
