Depends on the cause. Heel pain is most often caused by plantar fasciitis, a condition that is sometimes also called heel spur syndrome when a spur is present. Heel pain may also be due to other causes, such as infection, tendonitis, arthritis, stress fracture, nerve irritation, retained foreign body, bone tumor, or a cyst. Have it evaluated by a professional and get the appropriate treatment.
Plantar fasciitis. Heel pain can occur when the plantar fascia, a band of ligaments that attach from the heel to the forefoot, becomes inflamed due to a strain. Plantar fasciitis is usually treated conservatively (rest, ice, am stretching, anti-inflammatory meds, etc.) but confirm with you physician that this is the diagnosis.
