Achilles tendinitis is an overuse injury of the Achilles (uh-KILL-eez) tendon, the band of tissue that links calf muscles in the back of the leg into a heel bone.

Achilles tendinitis most commonly occurs in runners that have abruptly increased the intensity or length of their own runs. Additionally, it is typical in middle-aged men and women who play sports, like basketball or tennis, just on weekends.



Most instances of Achilles tendinitis may be treated with comparatively straightforward, at-home care beneath your physician's supervision. Self-care plans are often crucial to avoid recurring episodes. More-serious instances of Achilles tendinitis may result in tendon tears (ruptures) that might require surgical repair.

 Achilles Tendinitis Symptoms
The pain associated with Achilles tendinitis generally begins as a mild ache in the back of the leg over the heel after running or other sports action. Episodes of all more-severe pain may occur after prolonged jogging, stair climbing or sprinting.

You may also experience stiffness or tenderness, particularly in the early hours, which generally improves with gentle action.

Causes
Achilles tendinitis is caused by repetitive or intense strain on the Achilles tendon, the band of tissue that connects your calf muscles to your heel bone. This tendon is used when you walk, run, jump or push up on your toes.

The structure of the Achilles tendon weakens with age, which can make it more susceptible to injury — particularly in people who may participate in sports only on the weekends or who have suddenly increased the intensity of their running programs.

Prevention
While it may not be possible to prevent Achilles tendinitis, you can take measures to reduce your risk:

Increase your activity level gradually. If you are just starting an exercise regimen, then begin slowly and gradually increase the duration and intensity of your practice.
Take it easy. Avoid activities that place excessive stress on your tendons, such as hill running. If you participate in a strenuous activity, warm up first by exercising at a slower pace. If you notice pain during a particular exercise, stop and rest.
Choose your shoes carefully.
The shoes that you wear while exercising ought to offer sufficient cushioning for your heel and ought to have a firm arch support to lower the pressure of the Achilles tendon. Change out your shoes that are worn-out. If your shoes are in great shape but do not encourage your toes, attempt arch supports in the sneakers.
Treatment
Tendinitis usually responds well to self-care measures. But if your signs and symptoms are severe or persistent, your doctor might suggest other treatment options.

Medications
If over-the-counter pain drugs -- such as ibuprofen (Advil, Motrin IB, others) or naproxen (Aleve) -- are not enough, your physician may prescribe stronger drugs to decrease inflammation and alleviate pain.

Surgery
If several months of more-conservative treatments don't work or if the tendon has torn, your doctor may suggest surgery to repair your Achilles tendon.
