Severe sharp pains in pinky and ring fingers. Numbness in my wrist.?

It sounds like an ulnar nerve issue, which originates in the crook of your elbow. It usually results in numbness and tingling in those fingers. Carpal tunnel syndrome causes an impinging on this nerve which has the same effect. heat will NOT help. try using cold packs and take some time off if you can. see a doctor - it'll only get worse :(
