Penis bumps head and shalf help please

So i notice this bumps a year ago. It did not itch. I am sexually active at that time when i notice it. 3 months after i felt a itchines inside, split urination and burning urination, after one month it go away. I dont know if that was related to the bumps. But few days before that i was drinking to much alcohol. Few months after the burning urination and itchines inside i had a urinalysis and a CBC and it turns out to be normal. What are this bumps. And who should i see? A dermatology, urologist, etc? Thanks
