Thank you very much for your comments .
Hello,
It can be due to folliculitis skin or a cyst. You should wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove and warm compresses. Avoid any kind of cosmetics. Topical antibiotics such as mupirocin or neomycin containing ointment are also useful.
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.
