Achilles tendinitis is a common condition that causes pain on the back of the leg near the heel. The achilles tendon is the largest tendon in the body connecting your calf muscles to your heel bone. Your achilles tendon is used when you walk, run or jump. It is made to withstand a high amount of stress from these activities, but when it is overused, you can develop tendinitis. Tendinitis is defined as inflammation of a tendon. When you are injured, your body’s natural response causes inflammation. You may experience pain, swelling, or tenderness at the injured site. There are two types of achilles tendinitis, insertional and non-insertional achilles 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.
Patients with this condition typically experience pain in the region of the heel and back of the ankle. In less severe cases, patients may only experience an ache or stiffness in the Achilles region that increases with rest (typically at night or first thing in the morning) following activities which place stress on the Achilles tendon. These activities typically include walking or running excessively (especially uphill or on uneven surfaces), jumping, hopping, performing heel raises or performing calf stretches. The pain associated with this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. Pain may also increase when performing a calf stretch or heel raise (i.e. rising up onto tip toes). In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with Achilles tendonitis may also experience swelling, tenderness on firmly touching the Achilles tendon, weakness and sometimes palpable thickening of the affected Achilles tendon when compared with the unaffected side.
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don’t show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
See your doctor or sports physiotherapist for further advice. You may be prescribed anti-inflammatory medicine and a rehabilitation programme. Sometimes, the ankle may be put into a walking boot or cast to immobilise the ankle in the short term. Gentle calf stretching is the first stage of rehabilitation. Don?t stretch to the point of pain. Strengthening the Achilles tendon is the second stage. Your doctor or sports physiotherapist will be able to advise you on exercises for this. Special exercises called eccentric calf raises, that contract the calf muscle as it is lengthening (during the lowering part of the movement), are the standard exercise used in the rehabilitation of Achilles tendon injuries. Sometimes a heel raise or orthotics may be useful. As symptoms resolve, resume normal weight-bearing activities gradually. Avoid running until all tenderness has gone. Swimming or cycling in low gear are good replacement activities.
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.
By properly training the body, an athlete can build the strength of their tendons and muscles. Following a workout and dieting plan, the body will be able to build muscle and strengthen most effectively. Additionally, doing the following can prevent tendinitis. Wearing appropriate shoes will give your foot the support it needs for proper movements of the foot and ankle. Improper movements will put additional stress on your body. Stretching before an athletic activity, Stretching primes the body for a taxing activity. Additionally, this will get your blood flowing and reduce the risk of pulling a muscle. Ask your doctor about orthotics, Custom orthotics can help get your foot into proper alignment. If the foot does not execute proper mechanics, the body will adjust which will cause pain and increase the chances of injury.
