Question
For about a week now my pinky finger, left hand, has been numb at the tip. Sometimes it spreads to my ring finger and side of my hand. Once it went up my arm to right at my elbow. Do you have any suggestion on what this might be and how to fix it?

Answer
It sounds as if a nerve is pinched somewhere between the neck and hand.  I would suggest having a good chiropractor asses it, xray, and treat.  If anything more serious should be present, they should be able to explain that and refer you to the proper treatment.
