My family doctor say it is normal, but I used to not be this path. I am in my mid-40's. I have and EKG and they did not find anything wrong.When I exercise with gusto, my fingers tingle close to they are falling asleep. Why?
as you get elder, your blood cirulation gets worse, your fingures may not be getting enogh blood.
Blood is mortal directed to your muscles and not to your extremities, like your fingers. It's nought to worry nearly.
It sounds like a circulation problem to me. L-Arginine and Niacin are perfect for circulation. I take in the region of 500mg of Niacin a day and I enjoy noticed a big difference. I bring time released and try to find "non-flush" Niacin may make you quality flush. The L-Arginine you would probably take in the order of 1000mg or better. Make sure you are careful beside ANYTHING like that if you enjoy a poor medical history or use prescription drugs.
