Pain Behind The Heel, Especially With Activity
Achilles tendonitis is irritation, inflammation, or degeneration of the tendon that connects your calf muscles to your heel bone. It often starts as mild stiffness or aching after activity, then becomes harder to ignore when walking, running, stairs, hills, or pushing off the foot become painful.
🔥
Common Signs
Pain, stiffness, swelling, tenderness, thickening, or aching along the back of the heel or lower calf.
🏃
Common Triggers
Running, jumping, hills, stairs, sudden training increases, tight calves, poor footwear, and weekend sports.
⚠️
When To Call
A pop, snap, sudden weakness, trouble pushing off, worsening swelling, or persistent pain needs prompt evaluation.

Patient Guide To Achilles Tendonitis
This guide covers what Achilles tendonitis is, where it hurts, why it happens, how podiatrists diagnose it, conservative treatment, surgery when needed, rupture warning signs, recovery, prevention, and local care at Jayhawk Foot & Ankle Clinic.
Overview
The Achilles tendon is the strong band of tissue that connects the calf muscles to the heel bone. It helps you walk, run, climb stairs, jump, and rise onto your toes. Because it handles major force with every push-off, it is vulnerable to irritation and overload.
Achilles tendonitis, also spelled Achilles tendinitis, usually develops when the tendon is stressed faster than it can recover. It is common in runners, recreational athletes, people who suddenly increase activity, and middle-aged weekend athletes. It can also affect people who are not athletes, especially when tight calves, footwear, heel structure, or repeated strain keep loading the tendon.
Early Achilles tendonitis may feel like soreness or stiffness after activity. As it progresses, pain may occur during daily walking, stair climbing, or even at rest. Ignoring it can lead to chronic tendinopathy, tendon thickening, bone spur irritation, partial tearing, or full Achilles rupture.
What Is Achilles Tendonitis?
Achilles tendonitis is a painful overuse condition affecting the tendon behind the ankle. The tendon can become irritated, inflamed, swollen, thickened, or degenerative from repeated stress. Many clinicians use the broader term Achilles tendinopathy because not every case is purely inflammation.
There are two main patterns. Noninsertional Achilles tendonitis affects the middle portion of the tendon a few inches above the heel. Insertional Achilles tendonitis affects the lower tendon where it attaches to the heel bone and may overlap with heel spurs or Haglund’s deformity.
Achilles pain that keeps coming back? Schedule an appointment before tendon irritation turns into a longer recovery.
Symptoms often begin gradually and may come and go before becoming persistent. Common signs include:
Pain or aching along the back of the heel or lower calf.
Stiffness after rest, especially in the morning or after sitting.
Pain that worsens with running, sprinting, jumping, hills, or stairs.
Tenderness when squeezing or pressing along the tendon.
Swelling, warmth, or thickening around the tendon.
A bump or enlarged area on the tendon or back of the heel.
Tight calf muscles or limited ankle motion.
Pain when rising onto the toes or pushing off while walking.
Symptoms that improve with warm-up, then return after activity.
Severe pain, a sudden pop, bruising, weakness, or trouble walking can point to a tear or rupture and should be evaluated right away.
What Causes Achilles Tendonitis?
Achilles tendonitis usually develops from repeated overload. The tendon is asked to absorb more force than it is ready for, and small injuries can accumulate faster than the tissue heals.
Common causes and contributors include:
Sudden increases in running distance, speed, hills, or intensity.
Weekend sports after low weekday activity.
Tight calf muscles or poor ankle flexibility.
Training without enough recovery time.
Worn-out, unsupportive, or poorly fitting shoes.
Running on hills, hard surfaces, or uneven ground.
Flat feet, high arches, overpronation, or poor foot mechanics.
Bone spurs or Haglund’s deformity irritating the tendon insertion.
Age-related tendon stiffness and reduced tendon blood supply.
Certain medications or medical conditions that affect tendon health.
Insertional Vs Noninsertional Achilles Tendonitis
Insertional Achilles Tendonitis
Insertional Achilles tendonitis affects the point where the tendon attaches to the heel bone. Pain is usually low on the back of the heel. This type may be linked with heel spurs, calcification, bursitis, or shoe pressure at the back of the heel.
Noninsertional Achilles Tendonitis
Noninsertional Achilles tendonitis affects the middle part of the tendon above the heel. The tendon may feel thickened, tender, swollen, or nodular. This type is common in active adults and runners.
Who Is More Likely To Get Achilles Tendonitis?
Risk rises when tendon load, mechanics, recovery, or tissue health are out of balance.
Runners and athletes in jumping or cutting sports.
Middle-aged adults who play sports intermittently.
People who quickly increase training intensity or volume.
People with tight calves or limited ankle motion.
People with flat feet, high arches, or overpronation.
People who wear shoes without enough support or heel cushioning.
People with heel bone prominence, bone spurs, or Haglund’s deformity.
People with inflammatory arthritis or certain systemic conditions.
People with a previous Achilles injury.
How Achilles Tendonitis Is Diagnosed
A podiatrist starts with your symptoms, activity history, footwear, training changes, injury history, and where the tendon hurts. The exam checks swelling, tenderness, thickening, ankle motion, calf tightness, heel alignment, gait, and pain with resisted motion or toe rise.
Imaging is not always needed for a straightforward case, but it can be useful when symptoms are severe, persistent, recurrent, or concerning for tearing. X-rays can show heel spurs, calcification, Haglund’s deformity, or other bone problems. Ultrasound or MRI can help evaluate tendon thickening, degeneration, partial tearing, bursitis, or rupture.

Most cases start with non-surgical treatment. The goal is to reduce pain, calm irritation, protect the tendon, correct the overload pattern, and rebuild tendon strength without rushing back too soon.
Activity Modification
Temporarily reducing running, jumping, hills, speed work, or painful activity gives the tendon a chance to recover. Low-impact options like cycling, swimming, or controlled strength work may be safer during recovery, depending on symptoms.
Ice And Anti-Inflammatory Care
Ice after activity can help pain and swelling. Anti-inflammatory medication may be appropriate for some patients, but it should be used carefully and not as a way to push through worsening tendon pain.
Stretching And Strengthening
Calf stretching and progressive strengthening are often central to treatment. Eccentric heel-drop exercises may be used for many patients, but the right program depends on whether pain is insertional or noninsertional and how irritated the tendon is.
Heel Lifts, Orthotics, And Footwear
Heel lifts may reduce strain on the tendon in the short term. Supportive shoes, custom orthotics, or changes in training footwear may help when foot mechanics, overpronation, arch structure, or shoe pressure are contributing factors.
Immobilization
More painful cases may need a walking boot, brace, or temporary immobilization to calm the tendon before a gradual strengthening program begins.
Physical Therapy
Physical therapy may include stretching, strengthening, balance work, gait retraining, soft tissue care, and guided return-to-sport progression.
Are Steroid Injections Used?
Steroid injections around the Achilles tendon require caution because they may weaken tendon tissue and increase rupture risk in some situations. They are not a simple shortcut for Achilles pain. A podiatrist can discuss safer options based on the exact diagnosis and location of the problem.
When Surgery May Be Needed
Surgery is not the first step for most Achilles tendonitis cases. It may be considered when months of appropriate non-surgical care fail, when there is severe tendon degeneration, large bone spurs, significant insertional disease, or tearing that will not recover with conservative treatment.
Surgery may involve removing damaged tendon tissue, smoothing bone spurs, repairing or reattaching the tendon, or using nearby tendon tissue for support in severe cases. The right option depends on the location and severity of the damage.
Achilles Rupture Warning Signs
Achilles tendonitis and Achilles rupture are not the same thing, but chronic tendon problems can increase rupture risk. Seek urgent care if you notice:
A sudden pop, snap, or feeling like you were kicked in the back of the ankle.
Sudden sharp pain in the back of the ankle or calf.
Difficulty walking or pushing off the foot.
Weakness when trying to rise onto the toes.
New bruising, swelling, or a gap in the tendon.
Recovery And Return To Activity
Achilles tendonitis recovery can take weeks to months depending on severity, how long symptoms have been present, tendon degeneration, activity demands, and whether the cause is corrected. Pain often improves before the tendon is fully ready for higher loads.
A safe return usually means walking is comfortable, swelling is controlled, calf strength is improving, and sport-specific loading is reintroduced gradually. Returning too quickly is one of the most common reasons Achilles pain comes back.
Preventing Achilles Tendonitis From Coming Back
Prevention focuses on managing tendon load and improving the mechanics that overload the tendon.
Increase running distance, speed, and hills gradually.
Warm up before exercise and avoid sudden all-out activity cold.
Stretch tight calf muscles consistently.
Build calf strength progressively.
Rotate high-impact activity with lower-impact exercise when needed.
Wear supportive shoes that fit properly.
Replace worn-out athletic shoes.
Avoid training through worsening tendon pain.
Address flat feet, high arches, overpronation, or other mechanics when they contribute.
Achilles Tendonitis Care In Lenexa And The Kansas City Area
Jayhawk Foot & Ankle Clinic evaluates back-of-heel pain, Achilles tendon pain, sports injuries, tendon thickening, painful heel bumps, and recurring tendon problems. Care may include physical exam, imaging when needed, footwear review, heel lifts, orthotics, stretching and strengthening guidance, immobilization, and surgical consultation when appropriate.
If your Achilles pain keeps returning, is affecting walking or running, or came with a sudden pop or weakness, schedule an appointment before the problem gets worse.
It often feels like aching, burning, stiffness, tenderness, or swelling along the back of the heel or lower calf. Pain may be worse after running, stair climbing, sprinting, or getting up after rest.
Can Achilles tendonitis go away on its own?
Mild cases may improve with early activity changes and guided care, but persistent or recurring Achilles pain often needs evaluation so the cause is corrected before it becomes chronic.
Should I keep running with Achilles tendon pain?
Do not push through worsening tendon pain. Running through Achilles symptoms can prolong recovery and may increase the risk of tendon degeneration or tearing.
What is the difference between insertional and noninsertional Achilles tendonitis?
Insertional Achilles tendonitis affects the lower tendon where it attaches to the heel bone. Noninsertional Achilles tendonitis affects the middle portion of the tendon above the heel.
Do I need imaging for Achilles tendonitis?
Not always. A physical exam is often enough to start care, but X-rays, ultrasound, or MRI may be used when symptoms are severe, persistent, recurrent, or concerning for tearing.
When is Achilles pain urgent?
A sudden pop or snap, sharp pain, bruising, weakness, trouble walking, or inability to rise onto the toes can signal a tear or rupture and should be evaluated urgently.
Can orthotics help Achilles tendonitis?
They can help when foot mechanics, overpronation, arch structure, or heel position are contributing to tendon overload. A podiatrist can determine whether inserts, heel lifts, shoe changes, or custom orthotics make sense.
When should I schedule an appointment?
Schedule an appointment if Achilles pain lasts more than a short period, keeps returning, causes limping, worsens with activity, or is associated with swelling, thickening, weakness, or a painful heel bump.
