What causes white head pimple on the shaft of penis
Patient: I have what appears to be a white head pimple on the shaft of my penis. I popped it once but it has not disappeared. the skin is not reddened surrounding the pimple. it is sore if touched, it does not ooze. I am sexually active but I dont believe it is a genital wart. Doctor: Hello,  The pimple-like growth could be pearly penile papules. Nothing to worry. Just do not break it. Clean the penis regularly.  Hope I have answered your query. Let me know if I can assist you further.   Regards, Dr. K. V. Anand, Psychologist
