bacterial infection
"For a few days I had what I thought was a pimple in the opening of my right nostril. Finally I softened it with warm water and it popped. BIG MISTAKE! DONT DO IT!
Within a day the right nostril was reddish purple and swollen, my cheek bones hurt, my upper gums were enflamed, even my teeth hurt. There were now 3 more in my nose. I went to urgent care and Dr said it was cellulitis/staph infection, put me on Bactrim (2x's a day/10days) and topical (Mupirocin 2%) that can be used in nose even though it says not for internal use: mouth, nose, ears. 
This is my 5th dose, btwn day 2&3. Still in a lot of pain but original "pimple" seems to have a brownish coloring possibly on the way to scabbing
Definitely headache provoking, taking with Tylenol."
