What does pain in the back of the heel mean? This could indicate an injury to the Achilles Tendon, or the heel chord, of the foot.  It could be a tendinitis, which means an inflammation of the tendon, or it could mean something more serious such as a tear of the tendon.  Pain is never normal, so if you are having pain in the back of your heel, come in and make an appointment with one of our doctors today.
