I had the same problem...shooting pain when releasing the bar after heavy barbell curls. I took a couple days off and reduced the weight I used for curls right down. Should take about 2 weeks to get back in the game, but try and do some forearm work in the meantime, it helped me alot. But try and do forearms with your arms are hanging down, usually guys put their forearms on a bench and do forearm curls that way, but you can hang a barbell behind your back and do forearm curls without aggrevating anything
