Okay, I don't know what happened to the attached pic, but I uploaded it again but on my profile. I'm sorry if it seemed to graphic, but I thought it showed pretty well the bumps I was concerned about and it is hard to take good pictures from that area.
Hello,
There can be many possibilities for such bumps. It can be contact dermatitis, rash due to friction rub, folliculitis, cysts ,molluscum contagiosum(multiple, small, dome-shaped papules, often with a central depression or plug) or genital warts(caused by HPV infection).
Apply warm compresses, Neosporin ointment and calamine lotion and avoid messing with it. You can take anti-inflammatory pain killers like ibuprofen or acetaminophen. If the lumps persist then it will be best to get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
