My husband got a pimple on his butt that somehow got infected. the doctor gave him antibiotics and it evently closed up. A week later another pimple came right next to the other and he had to go back to the doctor. He keeps getting these pimples on his butt and inner thigh.They told him he had to have surgery on his sweat glands around his pulbic area.  This is where my concern comes in. About 2 months after I statred getting them. Is this something contagious I havent been to the doctor yet. they leave ugly black marks what am i to do.
