The tendon can be strained or suffer a minor tear at its attachment to the calcaneus. Sometimes the bursa between the tendon and the upper part of the bone becomes inflamed. In a chronic problem, spurs may form on the calcaneus. A spur can become detached, forming a focal point of pain. Achilles insertion problems can occur at any age. In children it is often linked to Sever’s disease.
What you Feel When you Have Achilles Tendon Insertion Strain
Pain usually comes on gradually, although it can happen suddenly. You feel pain on tiptoeing or running. The heel is tender when you press on it. In the early stages the pain may wear off when you are warmed up, but recurs later during your exercise. The tendon gradually tightens. There is little or no pain at rest unless there is direct pressure on the heel.
Causes for Achilles Tendon Insertion Strain
There is usually excessive strain on the calf in extreme ranges of movement, for instance when you run uphill as fast as you can. Shoes contribute if they have rough, uneven linings round the heel; if the heel counter is soft, tight or not the right shape for your foot; if the sole is hard; or if the heel has worn down unevenly.
Treatment for Achilles Tendon Insertion Strain
Check your shoes and discard any which chafe, if padding does not help. You may benefit from orthotics. Your doctor or specialist may offer you an injection.
