| Condition | Pain Location | Key Test | Aggravated By | Diagnosis | First Treatment |
|---|---|---|---|---|---|
| Non-insertional Achilles tendinopathy | Mid-tendon, 2–6cm above heel | Royal London test; pinch tenderness mid-tendon | Running; repetitive activity; morning stiffness | Clinical + ultrasound | Eccentric calf exercises; activity modification |
| Insertional Achilles tendinopathy | At calcaneal insertion | Tenderness at tendon-bone junction; thickening | Activity; stairs; heel lift provides relief | Clinical + X-ray + ultrasound | Heel lift; avoid toe-raises; eccentric at lesser range |
| Retrocalcaneal bursitis | Deep posterior heel (sides of Achilles) | Two-finger sign; fluctuance at insertion | Rigid heel counter shoes; direct pressure | Ultrasound (bursal fluid) | Open-backed shoes; heel lift; US-guided injection |
| Haglund’s deformity | Visible bony lump posterior-superior heel | Palpable osseous prominence; rigid bump | Rigid-backed shoes; high heels; running shoes | X-ray (parallel pitch lines) | Open-backed footwear; heel lift; surgical resection if chronic |
| Achilles tendon rupture | Sudden posterior heel; pop sensation | Thompson test positive; palpable gap | Acute event; unable to plantarflex | Clinical + MRI to assess extent | Non-weight bearing; splint; urgent surgical consultation |
| Calcaneal stress fracture | Diffuse posterior heel; worse with activity | Heel squeeze test; medial/lateral heel compression pain | Running; prolonged standing; new exercise | MRI (X-ray may be negative early) | Non-weight bearing or boot; restrict loading 6–8 weeks |
| Treatment | Best Condition | Timeline to Effect | Evidence Level |
|---|---|---|---|
| Heel lift (5–10mm) | All posterior heel conditions (reduces Achilles angle) | 1–2 days | High |
| Alfredson eccentric protocol | Non-insertional Achilles tendinopathy | 4–8 weeks for substantial relief | Highest (multiple RCTs) |
| Open-backed footwear | Retrocalcaneal bursitis; Haglund’s; insertional AT | Days | High (expert consensus) |
| Ultrasound-guided corticosteroid injection | Retrocalcaneal bursitis (bursa only; NOT tendon) | 1–2 weeks | Moderate |
| ESWT (shockwave therapy) | Chronic insertional AT; chronic non-insertional AT | 6–12 weeks (3 sessions) | High |
| PRP injection | Chronic Achilles tendinopathy; failed conservative care | 6–12 weeks | Moderate-High |
| Surgical resection (Haglund’s / bursectomy) | Chronic bursitis + Haglund’s after 6 months failed conservative | 8–12 weeks recovery | High (surgical outcomes) |
Quick answer: Back Foot Pain has multiple potential causes including mechanical, neurological, vascular, and inflammatory. The most common causes we identify are overuse, ill-fitting shoes, and biomechanical imbalance. Red flags requiring urgent evaluation: warmth/redness (infection), inability to bear weight (fracture), and unilateral swelling without injury (DVT). Call (810) 206-1402.

Back Of Foot Pain: Quick Answer
Pain at the back of your foot or heel can have very different causes than pain on the bottom or sides. We diagnose hundreds of “back of foot” pain cases monthly at Balance Foot and Ankle. Here are the 8 most common causes and what each means for treatment.
1. Achilles Tendinitis (Most Common)
Pain location: Along the Achilles tendon (back of lower leg into heel). Two types: Mid-portion (2-6cm above heel) – common in runners; Insertional (where tendon attaches to heel) – associated with Haglund deformity. Symptoms: Pain with first morning steps; worse with running, climbing stairs; thickened tendon. Treatment: Eccentric heel drops (Alfredson protocol), heel lifts, calf stretching, ice, sometimes shockwave or PRP for chronic cases.
2. Insertional Achilles Tendinitis
Pain location: Specifically at back of heel where Achilles attaches. Often associated with Haglund deformity (bone prominence on back of heel). Symptoms: Pain at back of heel; worse with rigid shoes, running uphill; visible bony prominence. Treatment: DIFFERENT from mid-portion Achilles – heel lifts, modified eccentric exercises (flat surface only), open-back shoes; surgery (Zadek osteotomy) for severe cases.
3. Haglund Deformity (Pump Bump)
What it is: Bony prominence on back of heel; often hereditary; may be aggravated by tight rigid shoes. Symptoms: Visible/palpable bump on back of heel; pain with shoe pressure (especially heels, ski boots, dress shoes); often combined with insertional Achilles tendinitis or retrocalcaneal bursitis. Treatment: Open-back shoes (clogs, sandals), heel pads, NSAIDs; surgery (Zadek osteotomy) for severe symptomatic cases.
4. Retrocalcaneal Bursitis
Pain location: Back of heel, between Achilles tendon and heel bone. Symptoms: Pain with shoe pressure on back of heel; swelling and warmth at back of heel; often combined with Haglund deformity. Treatment: Heel lifts, ice, NSAIDs, ultrasound-guided cortisone injection (NOT into Achilles itself – rupture risk), open-back shoes.
5. Achilles Tendon Rupture
Acute injury: Sudden severe pain at back of leg; “kick from behind” sensation; visible/palpable gap in tendon; cant rise on toes. Common in middle-aged athletes (basketball, tennis, soccer). Diagnosis: Clinical exam (Thompson test); MRI confirms. Treatment: Surgical repair OR functional bracing (similar outcomes with proper protocol); recovery 6-9 months for sport return.
6. Calcaneal Stress Fracture
Pain location: Diffuse heel pain; worse with weight bearing. Risk factors: Sudden activity increase, female athletes, military recruits, osteoporosis. Different from plantar fasciitis: doesnt improve with walking; may have night pain. Diagnosis: X-ray often misses early – MRI is gold standard. Treatment: Walking boot 6-8 weeks; gradual return over 12+ weeks.
7. Posterior Tibial Tendinopathy (Inside Heel)
Pain location: Inside of heel and ankle (medial). Symptoms: Pain with prolonged standing or walking; visible arch flattening; “too many toes” sign from behind. Treatment: Custom orthotics with deep heel cup and arch support; lace-up ankle brace; physical therapy; possibly surgical reconstruction for advanced cases.
8. Tarsal Tunnel Syndrome
Pain location: Inside of heel/ankle area; often radiates into arch. Symptoms: Burning, tingling, electric shocks; worse with prolonged standing. Diagnosis: Tinel sign at medial ankle; nerve conduction studies. Treatment: Custom orthotics, anti-inflammatories, gabapentin, surgical release for severe cases.
Diagnostic Approach
1. Detailed history: Specific pain location, onset, activities, prior injuries. 2. Physical exam: Palpation, range of motion, gait analysis, special tests for each diagnosis. 3. X-rays: for bony abnormalities, fractures. 4. Diagnostic ultrasound: for soft tissue conditions (Achilles, bursa). 5. MRI: for stress fractures, tendinosis, ligament injuries. 6. Nerve conduction studies: for tarsal tunnel syndrome.
When to See a Podiatrist
See us if: back of foot pain persists 2+ weeks; localized pinpoint tenderness; severe pain or “pop” sensation (rule out Achilles rupture); visible bony prominence; pain limits walking; recurrent same area pain. In-office diagnostic ultrasound can quickly differentiate causes. Same-week appointments at Balance Foot and Ankle. Schedule online.

Frequently Asked Questions About Back Of Foot Pain
What causes pain at the back of the foot?
Most common: Achilles tendinitis (mid-portion or insertional), Haglund deformity, retrocalcaneal bursitis. Less common but serious: Achilles rupture, calcaneal stress fracture, tarsal tunnel syndrome.
How do I tell Achilles tendinitis from Haglund deformity?
Achilles tendinitis: tender along tendon. Haglund deformity: visible bony prominence on back of heel; often combined with insertional Achilles tendinitis or bursitis.
Should I get a cortisone injection for back of heel pain?
AVOID injecting Achilles tendon itself – rupture risk. Cortisone may be appropriate for retrocalcaneal bursitis (different location) under ultrasound guidance.
When is back of foot pain an emergency?
Sudden severe pain with “pop” sensation, inability to rise on toes, visible gap in tendon = possible Achilles rupture – same-day evaluation. Cold pale foot suggests vascular issue.
What shoes are best for back of foot pain?
For Achilles tendinitis: heel lifts in stiff-soled shoes (Hoka Bondi, Brooks Beast). For Haglund deformity: open-back shoes (clogs, sandals). For tarsal tunnel: custom orthotics with arch support.
How long does Achilles tendinitis take to heal?
Acute: 4-8 weeks with proper treatment. Chronic tendinosis: 12+ weeks with eccentric protocol. Insertional: often longer than mid-portion. Surgical recovery: 4-8 months.
Should I keep running with back of foot pain?
Mild pain that resolves with rest: cautious continuation acceptable. Severe pain, sudden onset, inability to push off normally: stop and get evaluated.
