Hello,
Without examination,confirmation of a diagnosis is tough but it can be 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.
I sincerely hope that helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
sebaceous cysts. Normal, and nothing you can do about it. May even get much "worse". But, there's nothing wrong with you. It just happens to some people.
