try lightening up on your grip it may be the cause of the stress on your tendons. Once I lightened up on my grip my tendonitis eventually went away.

Specifically, what exercises are causing pain? I think the best exercise by far for tri's are heavy benches,,,,regular, with board, floor presses maybe.

I had this problem before and PB suggested that when I squat I extend my arms out all the way like I'm flying. Problem went away. Turns out when I would squat I had a really close grip w/ my hands about shoulder length apart so basically it was like I was trying to tricep press several hundred pounds and that put a lot of strain on the tendon.

whether you know it or not, most likely you do have an elbow ingury. If you have been training for few yrs, you probably developed it over time from doing bench presses, skull crushers, tricep pull downs, etc... you have got to keep away from locking when doing these excersises. Like i said, most likely this is what has caused your ingury. Any professional body builder will tell you the same thing, to keep away from locking. its very bad and hard on your elbows. Your elbows are made up of joint, ligaments, tendons, and bone. those ligaments and joints are extremly fragile and brittle and if mistreated, can be ingured easily. Id suggest hitting up a heating pad during the evenings and getting some glucosomine. Id just take it easy. when it comes to tricep training, do mostly pulldowns. stay away from overhead dumbbell extentions, dips, etc...as these put lots of stress on your elblows. Also, you can wrap them, and that will help with the pain. good luck bro, just dont push it to much until you are fully capable of doing so.

ice ibuprofen and rest.
