My skin have turned very black in color in my hip region . Also the skin appears very ciarse. It is also associated with itching. A few days back I had severe fever and during that time , the black skin had many scary like material on it and when I just lightly pressed it Pus came out.

After a week , the pus was gone. But now I again suffer from fever and also the black skin region have spread and increased pus have occured. It is very painful and itching . What disease do I have. Please help..
