Achilles tendon injuries include Achilles tendonitis, a condition of irritation and inflammation of the large tendon in the back of the ankle. Achilles tendonitis is a common injury that frequently occurs in middle-aged recreational athletes.
If you are experiencing painful swelling in the back of your foot just above the heel, you may be suffering from Achilles tendonitis. This troublesome condition affects the Achilles tendon, which is the strongest and largest tendon in the body and connects the leg to the foot as it stretches from the lower leg to the heel bone.
