I had a non-cancerous tumor removed from my calf 2 years ago. During the operation, one of the major arteries was severed. Since then - aside from numbness and pins and needles in my foot, I ve developed red freckles on the lower part of my leg. Is this related to the surgery, something normal, or something I need to worry about? I am a 54 year old female, started excercising 30 minutes a day 5 days a week about 6 months ago, walk 5 miles a day (according to the fitbit) and am an ex smoker.thanks.
