Hi Dr. um, i m a 17 year old female, and i ve noticed a bruise on my left leg. once i observed it closely, it does not seem like a ordinary bruise; it s dark purple and it seems like it has a some-what thick red line. This has not happened to me before. My mother died of stomach cancer , however, i m not sure if that will affect the situation. What is on my leg and how could i get rid of it?
