My finger nails are always a purple/deep blue color. Is this anything to worry about? I talked with my doctor about it, and he said it was normal, and said it was called something (Can't think of the name). I never notice the color of my nails until when I had my passing out spell and they said "her nails are so blue, and at one point the nurse told me it looked like a dead person finger nails). I compare mine to others and they have perfectly pink nails. I know it has something to do with ciruclation/enough oxygen. But, I feel fine. Is this common? My school nurse teacher acted like it was this HORRIBLE thing, but my family also has this problem. Is this anything to worry about? Can this be because of not eating meat? Or do I need to add something else to my diet. Help.
