What is the cause of wrist and forearm pain when I'm working out?!

What is the cause of wrist and forearm pain when I'm working out?

I have been weightlifting 4 days a week for almost a year. About two months ago I started to experience pain on my outer wrists (opposite my thumb) and about 3 or 4 inches up the outer side of my forearm. The pain doesn't come on during my reps, it's after I release the weight that I feel a sharp pain for about 5 or 6 seconds and then it subsides. After working out, it's sore for a few hours and then usually disappears. After 2 or 3 days of not working out, there is no pain or soreness at all. Bending my wrists foreward or back, left or right seem to cause no additional pain... it only happens when I release the weight and it only happens with certain exercises (especially barbell curls and some dumbell exercises). When I googled the problem people seemed to have similar issues, but nobody has a clear solution or diagnosis. Can anyone shed light?

I have the same problem! you need to keep your wrist in a neutral position when your lifting/ curling.when you flex your wrist your putting undo stress on your wrist and apposing thumb muscles-those muscles are taking some of your load.So not only are you not getting maximum lift in the muscle group your aiming for your also creating conditions for carpal tunnel and calcium cysts.I have the later and it sucks and is very painful.I lift now with gloves that have wrist restraints built in.I can no longer do yoga bridges,push ups -without either dumbells or props and it causes pain when i need to carry stupid things where I need to flex my wrists.Get the wrist supports!!! Not only will you get a better pump and muscle failure with better results, but you'll prevent and save yourself from surgeries to relieve a painful permanent condition. Good Luck!
