See the Dr.: You need an exam. you appear to have some sort of nerve entrapment syndrome such as possible carpal tunnel syndrome. Take NSAID's and use a wrist brace until you can see the Dr. Best wishes.

Carpal Tunnel?: Those are all symptoms of Carpal Tunnel syndrome. I would be checked by your doctor or an Urgent Care. You can take ibuprofen or aleve (naproxen) and use a wrist splint in the meantime as well.

See a doctor?: Hi, although the description is too vague but I think you might have inflammation of a nerve, possibly 2/2 overusing your hand due to typing, using computes or phone, See a doctor for evaluation.
