I have permanent AFib and CHF. I m doing well on meds, but have a lot of edema in my legs and feet. I ve noticed that my left leg and foot is more swollen than the right, and the toes tend to be dry, blueish in color, with pin-pricks of red dots on the top of that foot and the ankle. Only on my left foot, not the right. I ve tested negative for PAD. Your thoughts? Suggestions?
