I have a rash that started on my bikini line and has spread to my armpits, bends in my elbows and beds in my knees. It is extremely itchy and looks almost like pimples or hives. I have used jock itch cream and antibiotic cream which seems to help, some but I still have it after a month. I have also started spotting brown discharge in between periods. I want to think it's just a coincidence but I can't be sure.
