My husband is a peritoneal dialysis patient for 2 1/2 years, doing very well with his treatment. He has developed several small hard pimple-like areas, some on his chest and back, but lately on his penis. They usually do not open, but at times leak a small amount of clear fluid. His MD advised to put his Gentamyacin cream on these areas. It is very upsetting to him, esp those involving his genitals. What to do?
