Achilles Tendonitis

Overview
Achilles tendinitis is one of the more common causes of heel pain and many people describe it as pain in the back of the heel. Since this condition is a form of tendinitis, patients mostly notice that the back of their heel is inflamed. The Achilles tendon is the largest tendon in your body. It is also one of the most important and most used parts of the body. It is essential for walking, running, jumping or even just an extension of the foot. It is for this reason that Achilles tendinitis can affect anyone who is constantly putting stress on his or her foot. Athletes are particularly at risk.

Causes
A lot of stress on the feet is the cause of Achilles tendinitis. It is a common athletic injury. Things that can cause tendinitis include, pushing your body too fast and too soon, sudden increase in activity, sports that cause you to quickly start and stop, poor fitting shoes, bad footwear, severe injury to the Achilles tendon, running or exercising on uneven ground, running uphill, tight calf muscles, bone spur (extra bone growth in heel that rubs the tendon and causes pain), flat arches, feet that roll in (overpronation), and weak calf muscles, not warming up before exercising.

Symptoms
A symptom is something the patient feels and reports, while a sign is something other people, such as a doctor, detect. For example, pain is a symptom, while a rash is a sign. The most typical symptom of Achilles tendinitis is a gradual buildup of pain that deteriorates with time. With Achilles tendinitis, the Achilles tendon may feel sore a few centimeters above where it meets the heel bone. Other possible signs and symptoms of Achilles tendinitis are, the Achilles tendon feels sore a few centimeters above where it meets the heel bone, lower leg feels stiff or lower leg feels slow and weak. Slight pain in the back of the leg that appears after running or exercising, and worsens, pain in the Achilles tendon that occurs while running or a couple of hours afterwards. Greater pain experienced when running fast (such as sprinting), for a long time (such as cross country), or even when climbing stairs. The Achilles tendon swells or forms a bump or the Achilles tendon creaks when touched or moved. Please note that these symptoms, and others similar can occur in other conditions, so for an accurate diagnosis, the patient would need to visit their doctor.

Diagnosis
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.

Nonsurgical Treatment
Treatment will focus on relieving the pain and preventing further injury. Your podiatrist may create shoe inserts or a soft cast to effectively immobilize the affected area for a period of time. (Often, a couple of weeks are needed for the tendon to heal.) Medication can help too. Your podiatrist may recommend or prescribe oral medication.


Surgical Treatment
In cases of severe, long-term Achilles tendonitis the sheath may become thick and fibrous. In these cases surgery may be recommended. Surgery aims to remove the fibrous tissue and repair any tears in the tendon. A cast or splint will be required after the operation and a recovery program including physiotherapy, specific exercises and a gradual return to activity will be planned.

Prevention
Although Achilles tendinitis cannot be completely prevented, the risk of developing it can be lowered. Being aware of the possible causes does help, but the risk can be greatly reduced by taking the following precautions. Getting a variety of exercise - alternating between high-impact exercises (e.g. running) and low-impact exercise (e.g. swimming) can help, as it means there are days when the Achilles tendon is under less tension. Limit certain exercises - doing too much hill running, for example, can put excessive strain on the Achilles tendon. Wearing the correct shoes and replacing them when worn - making sure they support the arch and protect the heel will create less tension in the tendon. Using arch supports inside the shoe, if the shoe is in good condition but doesn't provide the required arch support this is a cheaper (and possibly more effective) alternative to replacing the shoe completely. Stretching, doing this before and after exercising helps to keep the Achilles tendon flexible, which means less chance of tendinitis developing. There is no harm in stretching every day (even on days of rest), as this will only further improve flexibility. Gradually increasing the intensity of a workout - Achilles tendinitis can occur when the tendon is suddenly put under too much strain, warming up and increasing the level of activity gradually gives your muscles time to loosen up and puts less pressure on the tendon.
