ICE! My DH had chronic tennis elbow for years, not from playing tennis at all, but from cutting down trees and cutting up said trees with a chain saw. Ice, rest, ibuprofen, and wearing straps helped, though it did take a long time to heal up. Every now and then it will still get irritated and bother him, but nothing like it used to. He used to ice his elbows twice a day for weeks on end.

Good luck -- it's a miserable thing!
