Medications and Toxins
Numbness and tingling in your fingers could be caused by medications you are taking or a toxic reaction from alcohol, lead or tobacco. If you have just started a new medication, that could very well be the culprit. You should consult your physician about this possibility. He may also be able to test your blood for toxins.
You may have an underlying medical condition that causes numbness and tingling in the fingers. Some specific conditions include carpal tunnel syndrome, diabetes, multiple sclerosis, underactive thyroid, Raynaud's phenomenon, vasculitis, frostbite, a pinched nerve or stroke. Your doctor can perform tests to determine if you have one of these or any other disease or condition.
If you experience tingling or numbness in your fingers for any reason other than your hand "falling asleep" occasionally, consult your physician as soon as possible for a diagnosis and treatment.
You should call 911 or get to a hospital immediately if you also have weakness or paralyis, if the symptoms are a result of an accident or injury, if you are unable to control movement of an arm or leg or if you experience any kind of disorientation, difficulty walking or speaking or vision problems.
