Hello. I have itchy brown spots on several parts of my body. One spot somewhere near my armpit where the arm flabs are and some on my calf. There's a large area of my breasts which has these itchy brown spots. Whenever they're touched lightly, they become itchy. When I scratch it, they become continuously itchy that I havce to force myself to stop scratching. When I scratch too much, they become red. Those on my legs even have scars now. The spots have been there for months and just won't go off. Is this something serious? What is causing this? Please help! I really need to put a stop to this...
