Hi There for the past 6 months I have had black spots appear around my legs, some of them are red and slightly inflamed. They seem to turn into black spots that are not going away. the picture I have taken is on the back of my leg between the knee. They seem to be there the most on both legs. I feel fine and have no apparent symptoms and am in pretty good health. I am male and am 36 yrs old - I smoke cigarettes but rarely drink. Any help or advice would be appreciated.
