Overview
Swelling and inflammation near a joint may be a sign of bursitis, a condition that involves buildup of liquid and inflammation in a bursa sac that cushions a joint. This condition has earned some interesting names over the years: housemaid?s knee, student?s elbow, and tailor?s bottom, to name a few. Simply put, bursitis is the inflammation of a bursa and buildup of fluid in the bursa sac. A bursa is a thin, slippery sac found around a joint that serves to reduce friction between bone and surrounding soft tissue, such as skin, muscles, ligaments and tendons. A bursa sac is made up of a synovial membrane, or synovium, that produces and contains synovial fluid. Excessive friction, a trauma, or other condition can irritate the synovium and cause it to become inflamed. The inflamed synovium will thicken and produce excess synovial fluid, and can cause symptoms such as localized swelling, skin redness and warmth, tenderness and pain. Of the approximately 160 bursae in the body, only a handful of them usually cause bursitis. These usual suspects are found in the knee, shoulder, elbow, and hip. Less frequently, bursitis may also occur in the heel, wrist, buttocks and big toe.

Causes
Posterior heel pain can come from one of several causes. When a physician is talking about posterior heel pain, he or she is referring to pain behind the heel, not below it. Pain underneath the heel, on the bottom of the foot, has several causes including Tarsal Tunnel Syndrome. Plantar Fasciitis. Heel Spurs.

Symptoms
Pain and tenderness are common symptoms. If the affected joint is close to the skin, as with the shoulder, knee, elbow, or Achilles tendon, swelling and redness are seen and the area may feel warm to the touch. The bursae around the hip joint are deeper, and swelling is not obvious. Movement may be limited and is painful. In the shoulder, it may be difficult to raise the arm out from the side of the body. Putting on a jacket or combing the hair becomes a troublesome activity. In acute bursitis symptoms appear suddenly, with chronic bursitis, pain, tenderness, and limited movement reappear after exercise or strain.

Diagnosis
Before making a diagnosis of retrocalcaneal bursitis, a doctor must rule out other possible problems, such as arthritis, a fracture or tumor. A doctor also will try to determine if the Achilles tendon itself is a source of pain. To make a diagnosis, a doctor will use some or all of the diagnostic tools below Patient interview. A doctor will ask a patient about medical history, and to describe the onset of his or her symptoms, the pattern of pain and swelling, and how symptoms affect lifestyle. For example, doctors may ask patients what types of shoes they wear and what they do for exercise. A patient's reported symptoms are important to diagnosis and treatment. The doctor will also ask what home treatments have helped the condition. Physical exam. A doctor will examine the patient's foot, noting swelling, tenderness and pain points, and range of motion. The doctor also may ask the patient to point and flex the feet and stand on his or her toes.

Non Surgical Treatment
Gradually progressive stretching of the Achilles tendon may help to relieve impingement on the subtendinous calcaneal bursa. Stretching of the Achilles tendon can be performed by having the patient place the affected foot flat on the floor and lean forward toward the wall until a gentle stretch is felt in the ipsilateral Achilles tendon. The stretch is maintained for 20-60 seconds and then is relaxed. Achilles stretch 1. The patient stands with the affected foot flat on the floor and leans forward toward the wall until a gentle stretch is felt in the ipsilateral Achilles tendon. The stretch is maintained for 20-60 seconds and then is relaxed. Achilles stretch 2. This stretch, which is somewhat more advanced than that shown in Images 1-2, isolates the Achilles tendon. It is held for at least 20-30 seconds and then is relaxed. To maximize the benefit of the stretching program, the patient should repeat the exercise for multiple stretches per set, multiple times per day. Ballistic (ie, abrupt, jerking) stretches should be avoided in order to prevent clinical exacerbation. The patient should be instructed to ice the posterior heel and ankle in order to reduce inflammation and pain. Icing can be performed for 15-20 minutes at a time, several times a day, during the acute period, which may last for several days. Some clinicians also advocate the use of contrast baths, ultrasound or phonophoresis, iontophoresis, or electrical stimulation for treatment of calcaneal bursitis. If the patient's activity level needs to be decreased as a result of this condition, alternative means of maintaining strength and cardiovascular fitness (eg, swimming, water aerobics) should be suggested.

Surgical Treatment
Surgery to remove the damaged bursa may be performed in extreme cases. If the bursitis is caused by an infection, then additional treatment is needed. Septic bursitis is caused by the presence of a pus-forming organism, usually staphylococcus aureus. This is confirmed by examining a sample of the fluid in the bursa and requires treatment with antibiotics taken by mouth, injected into a muscle or into a vein (intravenously). The bursa will also need to be drained by needle two or three times over the first week of treatment. When a patient has such a serious infection, there may be underlying causes. There could be undiscovered diabetes, or an inefficient immune system caused by human immunodeficiency virus infection (HIV).
