My finger keeps turning white and going numb, problem?!

Question: My finger keeps turning white and going numb, problem?

I was walking around out side and my finger went numb and white. You can see the difference from the finger next to it. Its not cold outside...50 degrees. 30 min later its still white and numb. About a month ago I was throwing a football with a buddy when all of the sudden I get a real sharp pain in the back of my head, I start seeing white spots and can hardly breathe. It went away after 20 min but now this too? Maybe related?

Answers:

Some people have cold extremities for no apparent reason. In others, the coldness stems from anxiety or stress. It's also a side effect of certain drugs, notably beta-blockers and many migraine-fighting drugs. However, if your fingers or toes temporarily turn white, the coldness is probably caused by Raynaud's disease, a common condition that impairs circulation to the extremities. Treatment includes stopping smoking, keeping the hands and feet warm, and if necessary, taking blood-vessel-dilating ACE inhibitors or calcium-channel blockers.
I hope this helps you. And good luck.
