Hypermobile Joints/elbows

Hi! I have been climbing for a while now - around two years. Lately i have gotten more and more pains in my elbows. They get worse when i do writing and alot of computer work too. And they also get really bad when i do crimping. Open hand climbing is somewhat better is seems. The pains are located on the outer side of the forearm, on the "tricep" side of the joint. It is worse in my right hand. I am also aware that i have quite hypermobile joints - so i wonder if this has something to do with the pains im experiencing? I have tried resting for weeks, but with little effect - it actually seems it gets better when i do really easy climbing. But the instant i do a little harder stuff, it gets bad again. what do i do? Is there any excersises, stretching, miracle cures or anything i can try do build up my joints so they get strong and let me climb with them? I eat omega-3 and vitamins for the gold medal by the way.. Thanks for any help.
