Between the heel bone and the plantar fascia is a small fluid filled sac that is called the plantar (bottom of) calcaneal (heel bone) bursa. The plantar calcaneal bursa?s job is to allow the plantar fascia to glide easily over the heel bone without irritation. If this becomes inflamed and irritated a plantar calcaneal bursitis occurs which can be extremely painful and disabling forcing the athlete to stop training.
Bursitis, tendinitis, and other soft tissue rheumatic syndromes typically result from one or more factors. These include: Play or work activities that cause overuse or injury to the joint areas Incorrect posture Stress on the soft tissues from an abnormal or poorly positioned joint or bone (such as leg length differences or arthritis in a joint) Other diseases or conditions (rheumatoid arthritis, gout, psoriasis, thyroid disease, or an unusual drug reaction) Infection.
Symptoms of bursitis include pain in the heel, especially with walking, running, or when the area is touched. The skin over the back of the heel may be red and warm, and the pain may be worse with attempted toe rise (standing on tippy-toes).
Bursitis is usually diagnosed after a careful physical examination and a full review of your medical history. If you garden and spend a lot of time on your knees, or if you have rheumatoid arthritis, tell your doctor, this information can be very helpful. During the physical exam, he or she will press on different spots around the joint that hurts. The goal is to locate the specific bursa that is causing the problem. The doctor will also test your range of motion in the affected joint. Other tests usually aren?t required to diagnose bursitis, but your doctor may suggest an MRI, X-ray or ultrasound to rule out other potential causes of pain.
Non Surgical Treatment
In addition to being aware of foot-wear and inserts, be sure to modify your activity level to reduce the pain initially. Taking non-steroidal anti-inflammatory drugs (NSAIDs) and icing twice a day for 20 minute periods can help reduce the swell that leads to heel pain. Cortisone injections (more powerful anti-inflammatory medications) can be considered if your symptoms are persistent. After the swelling and pain has receded, ask your podiatrist about working with a physical therapist to strengthen the affected area in order to avoid bursitis by using your muscles in a more safe and efficient manner. If all these treatment methods fail, surgery may be the best option to excise a painful bursa (note that this is in rare cases).
You can help to prevent heel pain and bursitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch of the foot and cushion the heel. If you are prone to plantar fasciitis, exercises that stretch the Achilles tendon (heel cord) and plantar fascia may help to prevent the area from being injured again. You also can massage the soles of your feet with ice after stressful athletic activities. Sometimes, the only interventions needed are a brief period of rest and new walking or running shoes.
