why do i have tight muscle aches in my back heel
Generally speaking, if the pain is under your heel bone it is likely plantar fasciitis. If the pain is found at the back of the heel, in the achilles or toward the base of the achilles (the long cord that extends from your calf to your heel bone), then it is likely achilles tendinitis. The pain from this condition is caused by inflammation of a thick tissue that begins at the heel and extends to the toes.
