Dermatology Questions? Ask an Online Dermatologist.
Hi and thanks for the question.
Do you have any pain, itching,or tingling on it.
Is it weeping?
Do you have any history of unprotected sexual encounter in the recent past?
Since this started as a pimple which was popped, and there is no history of tingling and pain in the area, this is most likely a infected hair follicle that burst open. You should observe it for a few days, apply bacitracin ointment on it twice daily, refrain from sexual intercourse and if it becomes painful then you should see your PCP.
Hope this helps.Please do leave a positive rating for the service.
