Most likely it is from trying to twists your wrists inward while curling and causing your forearm muscle to tense up and putting pressure on your bones. Try using dumbbells or an EZ curl bar. Flat bars cause me the same pain. And be careful to use only your biceps and not torquing your forearm. If you are going for mass, check out Jim Stoppani's program "shortcut to size". It was a game changer for me.
