Hi, few years back once I was wait in rain and for the couple of hours i had to stay in office with the wait cloths. After few days I found i had black spots between my upper legs, first i dint pay much attention on it. Now it s almost 4 years. The infection has increased a lot. Black spots between my upper legs, black spot on the upper back legs, itching and burning. I had been to few doctors but it didn t work out. Kindly advise me on this.
