the Achilles is not something to mess around with. if all that inflamation results in a tear you'll be off it for 6 months after surgery. chronic pain and swelling in a tendon as major as the Achilles is a very dangerous situation, see an orthopedic doctor. could be related to many causes, tight ITBs, tight hamstrings, etc. also, consider getting checked out by a sports massage therapist to see if your ITBs or hamstrings need to be released. meanwhile, no walks (make her ride) and plenty of ice. good luck and let us know.
