i my name Philip, I am 47 years old, I am 5'8" and weight 230 lbs., during the past few years I have noticed dark spots appearing on my lower legs (above and around my ankles). I don't feel any pain or itch, walking for few miles is not problem for me. I remember that my father has the same problem on his lower legs (who been past away for many years already), but my brother and sister don't have such problem on their legs. May I ask is it serious problem? Is there anything I need to concern with this symptom?
