Hello,
It can be due to Fordyce spots, clogged pores, irritated hair follicles or small cysts. Keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove. Avoid any kind of cosmetics. Topical antibiotics such as mupirocin or neomycin containing ointment are also useful. In case the symptoms persist then oral antibiotics may be needed. Please consult a dermatologist in that case.
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.
I have had that same thing. I went to my doctor some years ago and I was told it is a form of acne and completely harmless. She said not to pop them that they will either pop on there own or just go away. It is caused from heat and moisture, so they are like heat bumps and acne. So dont worry, you'll be ok. Unfortunately there isnt any treatment for them especially being in the genitals area you really cant put any creams down there. I would say try going to a dermatologist about it and see about any safer creams available. Good luck to you.
