have you tried shutting down the upper body lifts for a few weeks? I know its sucks to do so (I've shut down my upper body lifts for two weeks now to recover from bursitis in my shoulder), but it may be worth trying just to see if it alleviates the condition. FYI, I had tennis elbow back in college, but that was from serving a tennis ball too hard! When I laid off of playing tennis for a few weeks, the condition went away.

Tendonitis doesn't require surgery, torn ligaments do.

Looks like you are a doctor yourself so i don 't wanna diss on your profession . . . but I know of more than a few people who, as per their doctor's advice, got joint replacement surgery done . . . bad move . . . their pain got further aggravated without resulting in any significant change in range of motion/ability to bear stress etc. I am with Supertough in that surgery should probably only be used as a last resort.

I would probably try decreasing the weight you are using for your lifts and increase the reps/sets . . . as we grow older, our joints are unfortunately none the better for wear n tear . . . I had similar issues with my bench when I used to regularly hit 285/275 for sets in my earliey 20s. I eventually reduced the weight . . . voila, no more inflamation in the concerned joints!

Sounds like you have chronic tendinitis. When you get chronic tendinitis it is because of several reasons, which may include:
-you don't stretch
-you are lifting too much
-you are lifting too often
-you are genetically predisposed

Joint supplements won't help. Don't ever get surgery. Are you doing your PT exercises at home? are you still stretching? find a good PT who knows what he/she is doing. Your accessory muscles in the elbow may be weak and need to be developed properly. Once you get chronic tendinitis, sadly you live with it forever.
