Do you experience dull pain near the back of your heel or in the back of your leg after your regular run or after playing your favourite sport? When you ramp up your exercise is the pain more severe or prolonged? If so, you may have Achilles tendinitis. The Achilles tendon is the thick, strong, springy band of tissue that connects the muscles from the middle of your calf to your heel bone. You use your Achilles tendon when you walk, run or jump. Achilles tendinitis occurs when the Achilles tendon is repeatedly strained. The Achilles tendon becomes less flexible, weaker and more prone to injury as we age. Middle-aged weekend warriors and runners who suddenly intensify their training often suffer from Achilles tendinitis.
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.
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.
The recommended treatment for Achilles tendinitis consists of icing, gentle stretching, and modifying or limiting activity. Nonsteroidal anti-inflammatory medications (NSAIDs), such as ibuprofen or aspirin, can reduce pain and swelling. Physical therapy and the use of an orthotic (heel lift) can also be helpful. For chronic cases where tendinosis is evident and other methods of treatment have failed, surgery may be recommended to remove and repair the damaged tissue.
Around 1 in 4 people who have persisting pain due to Achilles tendinopathy has surgery to treat the condition. Most people have a good result from surgery and their pain is relieved. Surgery involves either of the following, removing nodules or adhesions (parts of the fibres of the tendon that have stuck together) that have developed within the damaged tendon. Making a lengthways cut in the tendon to help to stimulate and encourage tendon healing. Complications from surgery are not common but, if they do occur, can include problems with wound healing.
To prevent Achilles tendonitis or tendonosis from recurring after surgical or non-surgical treatment, the foot and ankle surgeon may recommend strengthening and stretching of the calf muscles through daily exercises. Wearing proper shoes for the foot type and activity is also important in preventing recurrence of the condition.
