That grinding stiffness in your heel when you take your first steps out of bed — or the burning pain that builds up during a run — is one of the most common overuse injuries we treat. Achilles tendinitis affects runners, weekend warriors, and anyone who’s increased their activity level too quickly. The frustrating part is how long it takes to heal if you try to push through it rather than address the load properly.
What Is Achilles Tendinitis?
The Achilles tendon is the thickest and strongest tendon in the body, connecting the gastrocnemius and soleus calf muscles to the calcaneus (heel bone). It transmits up to 8 times your body weight during running. Achilles tendinitis — more accurately called tendinopathy in modern sports medicine, since chronic cases show tendon degeneration rather than true inflammation — occurs when load exceeds the tendon’s capacity to adapt.
There are two anatomically distinct types: mid-portion tendinopathy (2–6 cm above the heel insertion, most common) and insertional tendinopathy (at the point where tendon meets bone, often involving a Haglund’s deformity). Treatment differs between the two.
Key takeaway: Mid-portion and insertional Achilles tendinopathy require different exercise protocols — correct diagnosis drives correct treatment.
Symptoms of Achilles Tendinitis
Classic presentations we see daily in our clinic include morning stiffness and pain that improves after 10–15 minutes of walking, a “warm-up” phenomenon where pain decreases during exercise then spikes afterward, localized tenderness along the tendon (pinch test), thickening or nodularity of the tendon in chronic cases, and creaking or crepitus with ankle movement. Pain specifically worse when walking uphill or climbing stairs suggests mid-portion involvement.
What Causes Achilles Tendinitis?
Achilles tendinopathy is fundamentally a load management problem — the tendon is asked to do more than it can currently handle. The most common cause we identify is a rapid increase in training volume or intensity. Other contributors: tight calf muscles (the most modifiable risk factor), sudden shoe change (especially to minimalist shoes), returning to activity after a period of rest, hill running, speed work, and age-related tendon stiffening in patients over 40. Fluoroquinolone antibiotics (ciprofloxacin, levofloxacin) are a non-mechanical risk factor that can trigger tendinopathy even at normal activity levels.
Key takeaway: Tight calf muscles are the single most modifiable risk factor — a consistent stretching and eccentric strengthening program addresses the root cause.
Achilles Tendinitis Treatment Options
The most evidence-based treatment for Achilles tendinopathy is the Alfredson eccentric heel drop protocol — a structured strengthening program that remodels the tendon over 12 weeks. Here’s the full treatment ladder:
- Load modification — reduce but don’t eliminate activity; complete rest leads to tendon weakening
- Eccentric heel drops — 3 sets of 15 reps, twice daily, on a step edge; the gold-standard exercise treatment per a 2023 Cochrane review
- Calf stretching — gastrocnemius (straight knee) and soleus (bent knee) stretching, 3x daily
- Heel lift inserts — reduce Achilles load immediately; especially helpful for insertional type
- NSAIDs — short course for acute flares (not long-term, as they may impair tendon healing)
- Physical therapy — guided progressive loading program
- PRP (platelet-rich plasma) injection — emerging evidence for chronic mid-portion tendinopathy
- ESWT (extracorporeal shockwave therapy) — effective for chronic insertional cases per multiple RCTs
- Surgery — tendon debridement for cases failing 6+ months of conservative care; rarely needed
The most common mistake we see is patients who rest completely until pain goes away, then return to full activity — only to have the pain return within days. The tendon needs progressive load to remodel properly. Complete rest is not the answer.
⚠️ When to see a podiatrist:
- You feel a sudden “pop” with acute onset of severe pain (possible rupture)
- You cannot rise on your toes on the affected leg
- Visible swelling or bruising appeared within hours of injury
- Pain is worsening despite 6 weeks of proper conservative care
- You are taking fluoroquinolone antibiotics and develop new tendon pain
Frequently Asked Questions
How long does Achilles tendinitis take to heal? Mid-portion tendinopathy typically takes 12–16 weeks of structured rehabilitation. Insertional tendinopathy can take longer — 16–24 weeks — because of bony involvement. Chronic cases (symptoms over 6 months) take longer but still respond well to proper treatment.
Should I stretch a painful Achilles? Gentle calf stretching is beneficial. However, aggressive stretching of an insertional tendinopathy can worsen the condition by compressing the tendon against the heel bone. Our team will guide you on the correct stretching protocol for your type.
Can Achilles tendinitis lead to a rupture? Chronic tendinopathy does increase rupture risk, though complete ruptures more often occur in tendons without prior pain. Any sudden pop with severe loss of push-off strength requires immediate evaluation.
The Bottom Line
Achilles tendinopathy is treatable — but only with the right kind of treatment. Passive rest doesn’t remodel tendon tissue; progressive loading does. If you’ve been dealing with that nagging heel pain for more than a few weeks, it’s time to get a proper diagnosis and start a structured program. Our team at Balance Foot & Ankle will confirm your tendinopathy type and build a rehabilitation plan that gets you back to running, not just walking.

🧴 Dr. Tom recommends for Achilles pain: Doctor Hoy’s Natural Pain Relief Gel
Arnica plus camphor formula applied directly to the Achilles tendon 3-4x daily provides topical relief during the healing phase. Unlike systemic NSAIDs, there is no GI risk. I use this in our clinic and recommend it as a safe adjunct to eccentric loading therapy. Apply after eccentric heel drops while the tendon is still warm.

👟 Orthotic support for Achilles recovery: PowerStep Pinnacle Insoles
Overpronation places excessive load on the Achilles at mid-stance. PowerStep Pinnacle insoles provide firm medial arch support that corrects the mechanical stress contributing to Achilles tendinopathy. I recommend these as the OTC orthotic most likely to complement your eccentric loading protocol — at a fraction of custom orthotic cost.
