I suffered with Achilles tendonitis for 2 years and the doctors and physical therapists wee making it worse. Then I meet a new PT who fixed the problem in one month with soft stretching exercises, walking different (I used to walk toe to heel) and Vitamin E Oil.
Try rubbing Vitamin E Oil in that area until it warms up once or twice a day, especially prior to exercise. The amount is whatever is enough to cover the area and soak through. Make sure to keep it warm after, fast cool downs of the tendon seem to cause problems.
