my veins in my hands have begun at night seem to bulge, become very prominant and ache so much so that sometime i cant' close my hands all the way and very often my hands look black and blue, i don't smoke, i exercise everyday, I am not overweight at all, very healthy..a have begun to have some very random aches and pains so much so that sometimes i can't sleep. I am very healthy 46 year old women that should not feel this way.
