Bursitis is inflammation or irritation of a bursa, a small sac located between a bone and muscle, skin, or tendon. The bursa allows smooth gliding between these structures. Below are some of the specific types of bursitis. Subacromial bursitis The subacromial bursa lies just above the rotator cuff. Bursitis often develops due to injury, impingement (pinching), overuse of the shoulder, or calcium deposits. Symptoms include pain in the upper shoulder or upper third of the arm, and severe pain upon moving the shoulder.
Causes of bursitis can be from any form of friction between bone and the soft tissues. The most common cause is due to abnormal pronation.
Retrocalcaneal bursitis is very similar to Achilles bursitis as the bursae are very close in proximity and symptoms are almost identical however retrocalcaneal bursitis is a lot more common. The symptoms of bursitis vary depending on whether the bursitis is the result of injury or an underlying health condition or from infection. From normal overuse and injury the pain is normally a constant dull ache or burning pain at the back of the heel that is aggravated by any touch, pressure like tight shoes or movement of the joint. There will normally be notable swelling around the back of the heel. In other cases where the bursa lies deep under the skin in the hip or shoulder, swelling might not be visible. Movement of the ankle and foot will be stiff, especially in the mornings and after any activity involving the elbow. All of these symptoms are experienced with septic bursitis with the addition of a high temperature of 38?C or over and feverish chills. The skin around the affected joint will also appear to be red and will feel incredibly warm to the touch. In cases of septic bursitis it is important that you seek medical attention. With injury induced bursitis if symptoms are still persisting after 2 weeks then report to your GP.
Gram stain. A lab test called a Gram stain is used to determine if certain troublesome bacteria are present. Not all bacteria can be identified with a Gram stain, however, so even if the test comes back negative, septic bursitis cannot be completely ruled out. White blood cell count. An elevated number of white blood cells in the bursa’s synovial fluid indicates an infection. Glucose levels test. Glucose levels that are significantly lower than normal may indicate infection.
Non Surgical Treatment
With anterior and posterior Achilles tendon bursitis, applying warm or cool compresses to the area and using nonsteroidal anti-inflammatory drugs (NSAIDs) can temporarily relieve the pain and inflammation, as can injections of a corticosteroid/anesthetic mixture into the inflamed bursa. The doctor is careful not to inject the mixture into the tendon. After this treatment, the person should rest. When these treatments are not effective, part of the heel bone may need to be surgically removed.
Surgery. Though rare, particularly challenging cases of retrocalcaneal bursitis might warrant a bursectomy, in which the troublesome bursa is removed from the back of the ankle. Surgery can be effective, but operating on this boney area can cause complications, such as trouble with skin healing at the incision site. In addition to removing the bursa, a doctor may use the surgery to treat another condition associated with the retrocalcaneal bursitis. For example, a surgeon may remove a sliver of bone from the back of the heel to alter foot mechanics and reduce future friction. Any bone spurs located where the Achilles attaches to the heel may also be removed. Regardless of the conservative treatment that is provided, it is important to wait until all pain and swelling around the back of the heel is gone before resuming activities. This may take several weeks. Once symptoms are gone, a patient may make a gradual return to his or her activity level before their bursitis symptoms began. Returning to activities that cause friction or stress on the bursa before it is healed will likely cause bursitis symptoms to flare up again.
Continue to wear your orthotics for work and exercise to provide stability and restore foot function. Select suitable shoes for work and physical activity that provide stability for the heel. Regular stretching of the calf muscle can prevent heel bursitis. Do not suddenly increase activity amount without appropriate conditioning.
