The OS didn't check for sinus communication, never even mentioned anything about that being a possibility, and like I wrote before I'm very frustrated and angry because he didn't cleaned the extraction site, and I'm afraid that is why I still have this on and off pain and the puffiness. I'm not having any other dental work done for right now, I will have to go back to this same OS to have the site re opened and cleaned. I asked him if he is going to send anything to pathology, he said yes if there is something suspicious, and I of course mentioned the antibiotic allergy, he didn't quite answer me.
