Achilles tendinitis is an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone.
Achilles tendinitis most commonly occurs in runners who have suddenly increased the intensity or duration of their runs. It’s also common in middle-aged people who play sports, such as tennis or basketball, only on the weekends.
Most cases of Achilles tendinitis can be treated with 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) that may require surgical repair.
ACHILLES TENDON ANATOMY
The pain associated with Achilles tendinitis typically begins as a mild ache in the back of the leg or above the heel after running or other sports activity. Episodes of more-severe pain may occur after prolonged running, stair climbing or sprinting.
You might also experience tenderness or stiffness, especially in the morning, which usually improves with mild activity.
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.
If over-the-counter pain medications — such as ibuprofen (Advil, Motrin IB, others) or naproxen (Aleve) — aren’t enough, your doctor might prescribe stronger medications to reduce inflammation and relieve pain.
A physical therapist might suggest some of the following treatment options:
Therapists often prescribe specific stretching and strengthening exercises to promote healing and strengthening of the Achilles tendon and its supporting structures.
A special type of strengthening called “eccentric” strengthening, involving a slow let down of a weight after raising it, has been found to be especially helpful for persistent Achilles problems.
A shoe insert or wedge that slightly elevates your heel can relieve strain on the tendon and provide a cushion that lessens the amount of force exerted on your Achilles tendon.
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.
