my dentist punctured my sinus cavity early sept, 9days ago drainage started out of the gum, Doc called in amoxicillin 500mg. Drainage stopped day before my pills were gone. Day after i ran out of antibiotics no drainage but started to smell bad smell, I finally figured it out, the smell is in my nose. Drove my self nuts thinking it was an abcess from one of my pets. It's been 4 days and now it's getting stronger its cross between rotting flesh and ammonia, it stinks, and stings just like ammonia sitting in front of me. I go back to dentist on Tuesday to have more extractions and I'm worried. What can I do about this in the meantime ? And will this affect the scheduled extractions? There is just not way I can get to the Dr to find out, but the off and on again smell is making me sick to my stomache.
