The : The ulnar nerve supplies sensation to the little finger side of your hand. The median nerve to the thumb side of your hand. These are two of the more common nerves to be affected. Common conditions are cubital tunnel, compressionof the ulnar nerve at the elbow and carpal tunnel, compression of the median nerve at the wrist, but these are not the only things that can cause a hand to fall asleep focal tingling can also represent a nerve root in the cervical splne ( your neck) or pressure on a specific nerve anywhere along the arm from shoulder down, in your axilla or armpit at the brachial plexus or furtehr on down to the nerves in your armor forearm. There are infections that can also cause tingling and sudden weakness. Swelling from an injury can also make the skin feel "numb" or less sensative to touch. If tingling or numbness is constant one should seek medical attention. Look for an orthopedic surgeon or hand surgeon in your area, or call your pcp to discuss this.

See your doctor.: This could be all one thing, or it could be 2 or 3 things. It could all be benign and easily treatable, or it could be something serious with long-lasting effects. You can't expect more from this forum than that. You need to see an actual live doctor in a real office for a thorough history and physical examination. Your guesses could be right or they could easily be wrong.
