Hello I read your statement and i understand you are concerned about pea size mass on base of your penis This lump can be due to irritation of the hair follicles due to continuous rubbing with clothes or a cyst. Please 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 please get it evaluated from a dermatologist and get cysts ruled out. 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 dermatologist. Treatment can be started only when the diagnosis is confirmed. I sincerely hope that helps. Take care and please do keep me posted on how you are doing. Thanks Dr Nasir Ali
