Heel pain is usually focused on the underside or the back of your heel. If your pain is on the underside of your heel, its likely cause is plantar fasciitis. Pain on the back of your heel, where the Achilles tendon attaches to the heel bone, is Achilles tendinitis. Although heel pain is rarely a symptom of a serious condition, it can interfere with your normal activities, particularly exercise.
