No more straight bar curls, those are what fucked my forearms up real good for a while. Just find some bicep exercises that don't trigger the pain and after a few weeks you will be able to go back to your normal routine again. I would suggest trying glucosamine and MSM (I haven't tried the MSM yet but will be getting some on my next order). I know it isn't joint pain but I can get by workouts pretty much pain free when I am on glucosamine (maybe psychological but I'll take it).
