What is Achilles Tendinitis?

Achilles tendinitis is an inflammation of the Achilles tendon, sometimes called the heel cord, which connects the calf muscles to the heel bone.

Achilles tendinitis is often a running injury or other sport-related injury resulting from overuse, intense exercise, jumping, or other activities that strain the tendon and calf muscles.
Achilles tendinitis is associated with heel or ankle pain, usually slow in onset, and a limp, causing trouble running and jumping. Exercise can make the symptoms either better or worse. The discomfort varies from being just a nuisance to being very painful and restrictive.

The back of the shoe may cause painful pressure on the attachment of the tendon to the heel bone. Sensitivity at the site of inflammation is a consistent sign. For noninsertional tendinitis, swelling is frequently seen and felt.

Most cases of Achilles tendinitis can be treated with persistent, relatively simple, at-home care under your doctor's supervision. Self-care strategies are usually necessary to prevent recurring episodes.

More serious cases of Achilles tendinitis can lead to tendon tears (ruptures) and may require surgery to repair damaged tissues.
