Hello, My name is Karissa and my age is 21 years old. I stand at 5 ft 3" and weigh in at 127 lbs. I exercise regularly and eat healthy. I have no health problems other than maybe poor circulation and am on the higher end of the scale for high blood pressure (150/80). I go tanning maybe once every 2 weeks and have done that on and off since i was 15. Just in the past month I started noticing these odd circles on the back of my left calf. Its like white spots with a red ring around them, they almost look vein like except that they are circular shaped and the all sit in a big cluster of around 30 circular spots/blotches, it covers around half of my calf and just happens right under the back of my knee, never touching near my ankle. I just noticed it happening the tiniest bit on my right one too, hardly at all though. They are there most of the time, sometimes more visible than others. It doesn't matter if im sitting or standing or working out for prolonger period of times. They are always there. They do not itch or burn or are raised. They have absolutely no affect on me what so ever other than they are unsettling to look at. I have not changed body creams, laundry detergent, gotten new clothes or started taking any new supplements or vitamins. What could this be? Should I worried enough to go in and see a Dr? Do you think they will go away?
