Retrocalcaneal and retroachilles bursitis are both common types of bursitis that can cause pain at the back of the foot, just above the heel. This pain, and often swelling, occurs when one or both bursae at the back of the heel become irritated and inflamed. Because they have similar symptoms, heel bursitis is sometimes confused with problems affecting the Achilles tendon, which is a long strip of fibrous tissue that connects the back of the heel to the calf muscle. Other times, Achilles tendon problems may bring about the bursitis. For example, tight calf muscles can contribute to chronic pulling where the Achilles tendon inserts into the back of the heel. This pulling can result in friction and irritation that eventually lead to bursitis.
The calcaneal bursa can become inflamed in patients with heel spurs or in patients with poor-fitting shoes (eg, high heels). Inflammation can occur secondarily from Achilles tendinitis, especially in young athletes. Patients exhibit tenderness to palpation of the bursa anterior to the Achilles tendon on both the medial and lateral aspects. They have pain with movement, which is worsened with dorsiflexion.
Symptoms of bursitis usually occur after rest and relaxation. Upon activity there is usually more intense pain in the area of the bursa. The common areas to have a bursitis in the foot are in the bottom of the heel, behind the heel near the attachment of the Achilles Tendon as well as along the side of a bunion. A bursa may also form in multiple areas especially along the metatarsal heads, or "ball" of your foot. You may actually feel the sac like fluid when rubbing the area of pain.
Carrying out a diagnosis for bursitis is fairly straightforward. The doctor will examine the affected area and ask the patient some questions about his/her recent activities. If the patient has a high temperature the physician may take a small sample of fluid from a bursa near the affected body part. The sample will be tested for bacteria, and perhaps also crystals. If the patient does not get better after treatment the doctor may carry out further tests so that he/she can eliminate the possibility that the symptoms might not be due to something else. These may include an x-ray, to make sure no bones are broken or fractured. Blood tests, to check for rheumatoid arthritis. A CT scan or MRI scan to see if there is a torn tendon.
Non Surgical Treatment
Medications may be used to reduce the inflammation and pain of retrocalcaneal bursitis. Nonsteroidal anti-inflammatory drugs such as ibuprofen, naproxen and ketoprofen can be purchased without a prescription and used to treat mild to moderate pain. These drugs are often used in combination with a physical therapy program or other retrocalcaneal bursitis treatments.
Surgery is rarely need to treat most of these conditions. A patient with a soft tissue rheumatic syndrome may need surgery, however, if problems persist and other treatment methods do not help symptoms.
