<s>[INST] hey i was curious about bumps the showed up on the side of my penisew thiere somewhat in a clump but then there one under my head of my penis and one by the hair area and its not herpes cause there no blisters there the same coler as my skin and cant pop i tried... any ideas? [/INST] Hi, The cause of such bumps depends on your age, pain and sexual activity. At age more than 40, associated with pain and bending, it may be Peyronie's disease. In younger age, it may be because of injury or simply skin boils or pimple. It's difficult to comment without examining it. Please get it checked by the doctor. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Sujoy Dasgupta, OB & GYN Specialist </s>
