Hi
Welcome to the MedHelp forum!
Sharp pain in one or the other hand can be due to pinched nerves, atherosclerosis of peripheral artery, deep vein thrombosis of a peripheral vein or due to carpal tunnel syndrome. You will need nerve conduction studies and color dopplar for confirmation.
Do discuss this with your doctor and get yourself examined. Take care!
