Hello,
Without examination,confirmation of a diagnosis is tough but it can be folliculitis, cysts, molluscum 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.
Sorry, I wanted to add to this after some searching.
I do have psoriasis if that at all matters.
It does kinda look like molluscum contagiosum as well.
