So, I noticed few days ago that my nails on fingers and toes are kind of between dark pink and purple to the middle.They don't hurt or anything else, just this. I've read that it could be a sign of cardiovascular diseases . Besides I used to have aches in legs and arms ,but when I was by the doctor last time, he said it's perhaps nothing bad. Besides I have always cold feet and hands even when I sit at home and I'm covered, but when I go out and it's cold they get warm. Anybody knows more about this, that would be helpfull?
