A heel spur is defined as a calcium deposit in the foot that causes a bony protrusion on the underside of the heel. Though some heel spurs are painless, they can cause heel pain. Some treatments may include exercise, custom-made orthotics, anti-inflammatory medications, and cortisone injections. In the event that conservative treatments fail, surgery may be necessary. Schedule an appointment with a physician at the Cleveland Foot & Ankle Clinic to develop a treatment plan.
