Noticed a Lump on Your Achilles Tendon? Here's What to Know
If you're experiencing lump on achilles tendon, you're not alone. This is one of the most common complaints we see at Lower Limb Clinic, and it's often a sign of Achilles Tendinopathy with Nodular Thickening or Insertional Calcification. The good news? With proper diagnosis and treatment, most patients experience significant improvement within 12-16 weeks for tendon remodelling.
Common Causes of Lump on Achilles Tendon
Achilles Tendinopathy with Nodular Thickening
Chronic tendon damage leads to abnormal tissue formation, creating a visible and palpable lump. This indicates the tendon has been under stress for some time.
Who typically experiences this: Those with long-standing Achilles pain, runners, middle-aged adults.
Insertional Calcification
Calcium deposits can form at the Achilles attachment to the heel, creating a hard lump at the back of the heel.
Who typically experiences this: Those with chronic insertional tendinopathy, older adults.
Without proper assessment, it's impossible to know exactly what's causing your lump on achilles tendon. What works for Achilles Tendinopathy with Nodular Thickening may not help—or could worsen—Insertional Calcification.
When Should You Seek Professional Help?
You should book an assessment if:
- You notice a new lump or thickening
- The lump is painful to touch or with activity
- The tendon looks different from the other side
- You have pain alongside the lump
"Most patients we see have tried various home remedies before booking. You're not wasting our time—persistent symptoms warrant professional assessment."
