severe sinus pain

Yesterday I went to the dentist because I had the worst pain of my life going on on a molar that had been root canalled and crowned a few years back,it hurt so bad I wanted them to yank it out of my mouth..They xrayed the mouth and saw nothing wrong with my teeth so as all week I have been having sinus problems they diagnosed me with sinusitis..as of yesterday afternoon I have been taking penicillin every 6 hours and I was given motrin 800's, pain is still so intense..a friend advised that claritin d worked good, I went and purchased a box and that didn't help..The pain is the worst pain I ever had in my life! Worse than child birth!! Its still so bad and I wonder why does it hurt so intensely bad? I am experiencing soreness on the right side of my face, like someone punched me on my cheek.. The top molars, mainly the root canalled tooth is excrutiating, right half of the roof of my mouth throbbing and sore, it won't give the pain will not stop and its so intense..please advise??

When my mother in law has sinus issues, it seems to affect her teeth as well. She says it's pretty painful, I (luckily) have never had that issue. But I agree that you should give the antibiotic time to do it's job and if by a week and a half you do not find relief, you should go back to the doctor. However, in the meantime, you should call your doctor to see about another pain med - perhaps one with codeine like Tylonel #3.

Alkcie, a dentist, and today I am feeling much better
