How do I treat interstitial tears of achilles tendon? I m a 69 yo male who has been inactive for about 1 year with resulting weight gain(about 25 lbs.!). Have been to several doctors with no great gain---tried boot which made my hip painful, foot soaking in mineral salts, resting foot, applying ice, etc. I used to walk every day with my wife for about 40 mins/day, work in my shop, play ping-pong, dance, etc. Am getting very discouraged. Any recommendations?
