I had a couple of bouts of tendonitis, one of which I'm trying to get rid of right now from an injury. Cherry juice is a natural anti-inflam. Plenty of water.

Massage esp. one that incorporates lymphatic drainage is very helpful. I will preface that by saying it is very hard to find a good therapist. I'm still trying to find one in Mass. that is good.

+1 on what Bleeker said about lifestyle. There is alot to be said about that. Stress is a nasty beast as well...
