I believe I have tendonitis as I am a drummer and my right achilles tendon has a certain tightness when I get done practicing. I am 67 and never have had this problem before? I think I also irritated the right foot tendon by excessive running! What remedies should i follow and do I have to stop exercizing? I do not need to take Tylenol unless that helps my rehab time. I am going to stop playing my bass drum to rest the tendon but do I have to stop exercising, maybe I can ride the stationary bike? Ken Genovesi
