In your heel, there is a sac filled with fluid known as a bursa. It is located under your Achilles tendon at the back of your heel bone. Many of your large joints have a bursa around them. They provide cushioning and lubrication for the tendons, muscles and bone. Bursitis of the heel occurs when the bursa in your ankle becomes swollen.
Occasionally the bursal sac can become inflamed and painful. Pain to the region is worse typically with initial weight bearing activity such as rising from bed in the morning. Swelling and warmth to the region are common. Clinical examination shows pain to palpation at the retrocalcaneus at a level just before the Achilles tendon. Increase pressure and friction of the Achilles tendon across the retrocalcaneal region is the cause of this bursitis. A high arch, tight Achilles tendon or bone spur appear to be some of the main causes of this problem. With a high arch the back portion of the calcaneus abnormally projects into the Achilles tendon region.
Medical experts strongly recommend that you consult a doctor if you have any of the symptoms below. Disabling joint pain that prevents you from doing your daily activities. Pain that lasts for more than two weeks. Excessive swelling, redness, bruising or a rash around the painful joint. Sharp or shooting pain, especially when you exercise or do something more strenuous. A fever. Any of the above could be a sign of infection, a condition such as arthritis or a more serious injury such as a tendon tear that may require medical attention.
When you suspect you have retrocalcaneal bursitis, your foot doctor will begin by taking a complete history of the condition. A physical exam will also be performed. X-rays are usually taken on the first visit as well to determine the shape of the heel bone, joint alignment in the rearfoot, and to look for calcium deposits in the Achilles tendon. The history, exam and x-rays may sufficient for your foot surgeon to get an idea of the treatment that will be required. In some cases, it may be necessary to get an ultrasound or MRI to further evaluate the Achilles tendon or its associated bursa. While calcium deposits can show up on xray, the inflammation in the tendon and bursa will show up much better on ultrasound and MRI. The results of these tests can usually be explained on the first visit. You can then have a full understanding of how the problem started, what you can do to treat prevent it from getting worse/ You will also know which treatment will be most helpful in making your heel pain go away.
Non Surgical Treatment
Treatment is primarily comprised of relief from the painful activity (running). It is important that shoes do not pinch the heel. If satisfactory progress is not made during the rehabilitation, medical treatment can be considered in the form of rheumatic medicine (NSAID) or injection of corticosteroid in the bursa. Injections should be performed under ultrasound guidance to ensure optimal effect and reduce the risk of injecting into the Achilles itself. If progress is not made neither through rehabilitation nor medicinal treatment, surgical treatment can be attempted.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
To prevent bursitis of the heel in the first place, always keep proper form during exercise. In addition, don?t jump into exercises that are too intense without building up to them. Strengthen and flex your ankle.
