This nagging injury can be long-lasting if not treated - and if your running form needs some work. The name Achilles is said to be a combination of two Greek words that together mean ?grief of the people.? The injury that bears that hero?s name, in honor of his only weakness, certainly aggrieves many runners, with Achilles tendinitis accounting for around 10 percent of running injuries. Technically, Achilles tendinitis is acute inflammation of the tendon that runs along the back of the ankle. Pain in that area for longer than a couple weeks is not really tendinitis anymore. Athletes, however, tend to characterize any pain along the tendon above the back of the heel as Achilles tendinitis. Achilles tendinitis can be confused with other injuries, such as heel problems, but the hallmark sign is if you?re pinching the Achilles and it?s really sore.
Achilles tendinitis can be caused by any activity that puts stress on your Achilles tendon. Tendinitis can develop if you run or jump more than usual or exercise on a hard surface. Tendinitis can be caused by shoes that do not fit or support your foot and ankle. Tight tendons and muscles, You may have tight hamstring and calf muscles in your upper and lower leg. Your tendons also become stiffer and easier to injure as you get older. Arthritis, Bony growths caused by arthritis can irritate the Achilles tendon, especially around your heel.
The symptoms associated with Achilles tendonitis and tendonosis include, Pain-aching, stiffness, soreness, or tenderness-within the tendon. This may occur anywhere along the tendon?s path, beginning with the tendon?s attachment directly above the heel upward to the region just below the calf muscle. Often pain appears upon arising in the morning or after periods of rest, then improves somewhat with motion but later worsens with increased activity. Tenderness, or sometimes intense pain, when the sides of the tendon are squeezed. There is less tenderness, however, when pressing directly on the back of the tendon. When the disorder progresses to degeneration, the tendon may become enlarged and may develop nodules in the area where the tissue is damaged.
The diagnosis is made via discussion with your doctor and physical examination. Typically, imaging studies are not needed to make the diagnosis. However, in some cases, an ultrasound is useful in looking for evidence of degenerative changes in the tendon and to rule out tendon rupture. An MRI can be used for similar purposes, as well. Your physician will determine whether or not further studies are necessary.
Tendon inflammation should initially be treated with ice, gentle calf muscle stretching, and use of NSAIDs. A heel lift can be placed in the shoes to take tension off the tendon. Athletes should be instructed to avoid uphill and downhill running until the tendon is not painful and to engage in cross-training aerobic conditioning. Complete tears of the Achilles tendon usually require surgical repair.
Surgery usually isn't needed to treat Achilles tendinopathy. But in rare cases, someone might consider surgery when rubbing between the tendon and the tissue covering the tendon (tendon sheath) causes the sheath to become thick and fibrous. Surgery can be done to remove the fibrous tissue and repair any small tendon tears. This may also help prevent an Achilles tendon rupture.
Maintaining strength and flexibility in the muscles of the calf will help reduce the risk of tendinitis. Overusing a weak or tight Achilles tendon makes you more likely to develop tendinitis.
