Went to bed last night with a tooth ache - was surprised cause nothing is wrong with the tooth. And then about midnight it came to me dummy it isn't a tooth ache, you are getting a sinus infection!!! Drainage down the back of my throat - when I sat up it drained and my tooth didn't hurt but when I layed down I was in terrible pain! Needless to say it was a long night....... MY head is filling up again this morning. I have called the PCP but she is off today and won't be back until Monday.
