Throbbing Back of the Ankle After Exercise? Achilles Tendinitis Can Become Serious If Ignored

Does your heel prickle every morning when stepping out of bed, and does the back of your ankle throb so much after exercising that it is hard to walk? If your pain is worsening even though you do not remember spraining your ankle, this might not be simple muscle pain, but a warning sign sent by your body. It is very likely Achilles tendinitis.
