What could be causing the severe pain in my foot?

Any # of things: Heel pain can result from a number of different reasons. I would seek the attention of an orthopedic foot and ankle surgeon. One in your area can be found at www.Aofas.Org.

Foot pain: Foot pain can be caused by a variety of medical problems. You should be examined by your family doctor or podiatrist. One possible cause is heel spurs or plantar fasciitis. Another one could be a nerve entrapment. You need to be examined and give more information on what type if pain you are experiencing and what medical conditions you have.
