I have ant-bite like sores in and on the edges of my nostrils. They are poppable and full of clear pus. They are really painful and itchy. I had tonsillitis about two or three weeks ago and finished my antibiotics (10 days, 850 amox) . I have had a cold this week and just began my period. I don't know what to do or how to get rid of them but they hurt very badly and the only relief I get is if I pop them, but some are hard to reach. Do I keep popping? Do I need a doctor??
