Achilles tendonitis is inflammation of the tendon, usually resulting from overuse associated with a change in playing surface, footwear or intensity of an activity. The Achilles tendon is surrounded by a connective tissue sheath (paratenon, or ‘paratendon’), rather than a true synovial sheath. The paratenon stretches with movement, allowing maximum gliding action. Near the insertion of the tendon are two bursae – the subcutaneous calcaneal and the retrocalcaneal bursae.
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 pain associated with Achilles tendonitis can come on gradually or be caused by some type of leg or foot trauma. The pain can be a shooting, burning, or a dull ache. You can experience the pain at either the insertion point on the back of the heel or upwards on the Achilles tendon within a few inches. Swelling is also common along the area with the pain. The onset of discomfort at the insertion can cause a bump to occur called a Haglund’s deformities or Pump bump. This can be inflammation in the bursa sac that surrounds the insertion of the Achilles tendon, scar tissue from continuous tares of the tendon, or even some calcium buildup. In this situation the wearing of closed back shoes could irritate the bump. In the event of a rupture, which is rare, the foot will not be able to go through the final stage of push off causing instability. Finally, you may experience discomfort, even cramping in the calf muscle.
To diagnose the condition correctly, your doctor will ask you a few questions about the pain and swelling in your heel. You may be asked to stand on the balls of your feet while your doctor observes your range of motion and flexibility. The doctor may also touch the area directly. This allows him to pinpoint where the pain and swelling is most severe.
In addition to stretching, using a foam roller and getting regular massage to keep the joint mobile can help prevent any problems from starting. If you start to feel inflammation in your tendon or have Achilles tendinitis once, it isn?t necessarily the end of the world. Let it rest and recover, which can sometimes take as long as four to six weeks if you waited until the pain was acute. The real problem is if Achilles tendinitis becomes an ongoing injury. If it keeps recurring, then it?s time for the perpetually injured to examine what they?re doing to cause the problem.
Occasionally, conservative management of Achilles tendon conditions fails. This failure is more common in older male patients and those with longstanding symptoms, those who persist in full training despite symptoms or those who have uncorrected predisposing factors. In these cases, surgery may be indicated. It should be remembered, however, that the rehabilitation program, particularly for severe Achilles tendon injuries, is a slow, lengthy program. Surgery is only indicated when there is failure to progress in the rehabilitation program. Surgery should not be considered unless at least six months of appropriate conservative management has failed to lead to improvement.
Wear shoes that fit correctly and support your feet: Replace your running or exercise shoes before the padding or shock absorption wears out. Shock absorption greatly decreases as the treads on the bottoms or sides of your shoes begin to wear down. You may need running shoes that give your foot more heel or arch support. You may need shoe inserts to keep your foot from rolling inward. Stretch before you exercise: Always warm up your muscles and stretch gently before you exercise. Do cool down exercises when you are finished. This will loosen your muscles and decrease stress on your Achilles tendon. Exercise the right way: If your tendinitis is caused by the way that you exercise, ask a trainer, coach, or your caregiver for help. They can teach you ways to train or exercise to help prevent Achilles tendinitis. Do not run or exercise on uneven or hard surfaces. Instead, run on softer surfaces such as treadmills, rubber tracks, grass, or evenly packed dirt tracks.
