Bursa is a fluid filled sac of tissue that is often found around the bony prominences over which tendons and soft tissues rub. This therefore helps the tendons to glide with least amount of friction. Retrocalcaneal bursa is found behind the heel under the Achilles tendon. Retrotendoneal bursa is found on the back of the attachment of the tendon where the shoe rubs on the skin. This can cause swelling, pain and difficulty in footwear. Sometimes there is a bony prominence on the heel bone that predisposes to this condition (Haglund?s deformity). Treatment of this can be modification of footwear. However surgery is often required which involves excision of the bursa and also the bony prominence on the heel bone.
There are several factors which can lead to a person developing retrocalcaneal bursitis. In athletes, especially runners, overtraining, sudden excessive increase in running mileage may lead to retrocalcaneal bursitis. Tight or ill-fitting shoes can be another causative factor as they can produce excessive pressure at the back of the heel due to restrictive heel counter. A person with an excessively prominent posterosuperior aspect of the heel bone (Haglund deformity) may also have a higher predisposition to retrocalcaneal bursitis. In such individuals, pain would be reproduced when the ankle goes into dorsiflexion.
Limping. Decreased movement. Your ankles may feel stiff or unable to move as well as they usually do. Pain or tenderness in the back of the ankle. It may be worse at the beginning of exercise, or when running uphill. You may also have pain when wearing shoes. Redness and warmth. If the bursa is infected, the skin over the heel may be red and warm. You may also have a fever. Swelling on the back of the heel.
A physical examination will be performed to determine if you have any signs of Achilles Bursitis or other ankle injury. He/she will look and feel the soft tissue and bones in your ankles to note any differences between the two of them. This will identify any abnormalities, such as swelling, bone deformities, atrophied muscles, redness and/or warmth on the skin. In many cases, the first sign that you have Achilles bursitis is swelling in the back of the foot and ankle pain.
Non Surgical Treatment
The initial course of treatment for this problem, after the usual ice and ibuprofen/aspirin routine or course, is to change footwear, especially if the onset of the problem was coincidental with a new pair of shoes. If this fails, a small heel lift (no more than ??) in both shoes may provide enough biomechanical adjustment to relieve the stress and/or friction over the area. If there is still no improvement, complete rest from running is probably advised, along with a professional consultation.
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.
