I have been having a problem with itchy skin, now particularly in the groin area. About a week ago, 3 red bumps appeared on my scrotum . I saw my family doctor and he said it was probably follicitus and gave me Keflex. The last few mornings, the groin area itch is very intense in the mornings, almost unbearable, then gets better, Also,slight rash in the buttock area. What can I do to get rid of this?
