Hello,
From the symptoms that you have mentioned these small bumps that you had on your penis sound like Fordyce spots which are a form of ectopic sebaceous gland. Since now hair are arising from them, it can be infected hair follicles or sebaceous cysts. 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 dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
