what are signs of heart disease in women. runs in my family. I have 4 purple toenails that happened a week ago. keep having swelling of hands legs and feet. saw my doctor today and she said it was from standing on my feet so much and arteries could not get blood flow back up. I set much of last nite at work and have been sitting now. Legs and hands are steady swelling. no salt in diet and only eat lean turkey as a meat. yogurt and fruit for breakfast. mother and brother died from heart attacks.
