Bursae (two or more bursa) are small, fluid-filled sacs that cushion the bones, tendons and muscles surrounding your joints. They contain a lubricating fluid that reduces friction, allowing tissues in the body to glide past each other smoothly. Imagine the bursa as a protective layer that helps keep a tendon or muscle from fraying or getting aggravated as it eases over a bone or around a corner. Bursitis is a condition that occurs when a bursa becomes inflamed: irritated, red and filled with more fluid than normal.
Bursitis can be caused by an injury, an infection, or a pre-existing condition in which crystals can form in the bursa. Injury. An injury can irritate the tissue inside the bursa and cause inflammation. Doctors say that bursitis caused by an injury usually takes time to develop. The joints, tendons, or muscles that are near the bursae may have been overused. Most commonly, injury is caused by repetitive movements.
Bursitis usually causes a dull pain, tenderness, and stiffness near the affected bursa. The bursa may swell and make the skin around it red and warm to the touch. Bursitis is most common in the shoulder camera.gif, elbow camera.gif, hip camera.gif, and knee camera.gif. Bursitis may also occur near the Achilles tendon or in the foot. Symptoms of bursitis may be like those of tendinopathy. Both occur in the tissues in and around the joints. Check with your doctor if your pain is severe, if the sore area becomes very hot or red, or if you have a fever.
Your doctor will check for bursitis by asking questions about your past health and recent activities and by examining the area. If your symptoms are severe or get worse even after treatment, you may need other tests. Your doctor may drain fluid from the bursa through a needle (aspiration) and test it for infection. Or you may need X-rays, an MRI, or an ultrasound.
Non Surgical Treatment
Long Term Treatment must be directed towards eliminating the abnormal tilting of the heel, regardless of its cause. If this is delayed, the usual results are the pain and swelling becomes worse, chronic, and debilitating. Eventually, painful calcifications and bone spur formations may occur on the back of the heel, along with tears in the Achilles Tendon. These are serious problems that may require surgical intervention. In order to eliminate abnormal heel tilt, the foot must be re-balanced. Controlling and reducing the biomechanical foot defects that are causing the heel to tilt best accomplish this. The "Gold Standard" of medical care (that treatment most used by doctors and therapists) to help eliminate pain, inflammation, and swelling at the back of the heel is orthotics.
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.
