Tendinitis is the inflammation of a tendon. Tendons are thick cords of tissue that connect muscles to bone. Achilles tendinitis, or an inflammation of the Achilles tendon, is one of the most common causes of foot or ankle pain. Other types of foot/ankle tendinitis include posterior tibial tendinitis and peroneal tendinitis.
There are two large muscles in the calf. These muscles are important for walking. They create the power needed to push off with the foot or go up on the toes. The large Achilles tendon connects these muscles to the heel. Heel pain is most often due to overuse of the foot. Rarely it is caused by an injury. Tendinitis due to overuse is most common in younger people. It can occur in walkers, runners, or other athletes. Achilles tendinitis may be more likely to occur if you Suddenly increase the amount or intensity of an activity. Your calf muscles are very tight (not stretched out). You run on hard surfaces such as concrete. You run too often, you jump a lot (such as when playing basketball), you do not have shoes with proper support, your foot suddenly turns in or out. Tendinitis from arthritis is more common in middle-aged and elderly people. A bone spur or growth may form in the back of the heel bone. This may irritate the Achilles tendon and cause pain and swelling.
People with achilles tendinitis experience mild aching on the back of the leg close to the heel after increased activity. Stiffness in the back of the ankle when you first wake up in the morning, which subsides after mild activity. In some cases, the area may have swelling, thickening or be warm to the touch. Tenderness to touch along the tendon in the back of the ankle. Pain when the tendon is stretched (i.e. when you lift your foot/toes up).
Confirming Achilles tendonitis may involve imaging tests. X-rays provide images of the bones of the foot and leg. Magnetic resonance imaging (MRI) is useful for detecting ruptures and degeneration of tissue. Ultrasound shows tendon movement, related damage, and inflammation.
Treatment options might include anti-inflammatory medication such as ibuprofen which might help with acute achilles inflammation and pain but has not been proven to be beneficial long term and may even inhibit healing. If the injury is severe then a plaster cast might be applied to immobilize the tendon. Use of electrotherapy such as ultrasound treatment, laser therapy and extracorporeal shock wave therapy (ESWT) may be beneficial in reducing pain and encouraging healing. Applying sports massage techniques can mobilze the tissues or the tendon itself and help stretch the calf muscles. Some might give a steroid injection however an injection directly into the tendon is not recommended. Some specialists believe this can increase the risk of a total rupture of the tendon in future. One of the most effective forms of treatment for achilles tendonitis is a full rehabilitation program consisting of eccentric strengthening exercises. There is now considerable evidence suggesting the effectiveness of slow eccentric rehabilitation exercises for curing achilles tendon pain.
Surgery is considered the last resort. It is only recommended if all other treatment options have failed after at least six months. In this situation, badly damaged portions of the tendon may be removed. If the tendon has ruptured, surgery is necessary to re-attach the tendon. Rehabilitation, including stretching and strength exercises, is started soon after the surgery. In most cases, normal activities can be resumed after about 10 weeks. Return to competitive sport for some people may be delayed for about three to six months.
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.
