It is important to understand that all heel pain is not from plantar fasciitis. Other medical problems can cause foot and heel pain. Diabetes and blood vessel disease, both serious medical problems, can cause heel pain. Arthritis, traumatic injury and bruising, gout, stress fractures (caused by repeated stress on bone), and other diseases can also cause heel pain. Rarely, tumors (either benign or cancerous) or infections can cause heel pain. If you develop persistent heel pain, see your doctor for an evaluation.
