Do people actually use antibiotic cream for piercings?? Or go to the doctor?

I got called stupid because I said I didn't understand going to the actual doctor for a piercing that isnt healing right... they said "you clearly have no piercings" umm. i have 7 piercings and havent gone to the doctor for a single one. You arent supposed to use creams to try to heal them... sooo whats your opinion on this?
