So to begin, the tooth started as a root canal about 10 years ago, was supposed to get a crown on it but my father couldn't afford it so it stayed with just a filling, last year filling fell out(yes I know should have taken care of it but I couldn't afford it) so it's been sitting for a year without a filling, I've tried to keep it as clean as possible. But it abscessed. Of course. So said forget it and got it removed 2 days ago since it was killing me, come to find out it was going into my sinus. (It's a molar on my top left). A couple days before my nose was actually bleeding when I blew it. But now, tooth is gone I'm on amoxicillin, and I feel very nauseous. I'm not on any pain killers and I've been eating as much soup as my stomach allows. I was wondering if this is normal for the situation? My sinuses have been draining and I've been coughing a lot(taking a decongestant as dentist told me to) I don't ever get sick. So I'm miserable right now.
