I found a wonderful new dentist that is going to start repairing 10 years of damage from my previous dentist who apparently wasn't doing a very good job. I went in for a crown that had became loose and painful. The dentist prepared the tooth for a new crown but said it was a 50/50 chance that I would need a root canal (and the pain during the prep was pretty intense, but I cannot have epinephrine). He is on vacation for another week and a half, but I have been having bad pain since he did the temp. The pain radiates up my jaw and into my head. I have had a horrible pressure headache for the last few days and I don't know if it is a by-product of Tylenol and Advil, or if it is just the nerve that obviously needs a RC. The pain is wearing me down and I feel nauseous and sick. I have fibromyalgia, so my nerves and reactions to medical problems are always intensified as it is, so I tend to minimize how serious everything is. However, this time I am feeling so bad and I cannot wait another week and a half. I don't know if this is normal and simply needs the RC or if it sounds like an infection may be coursing through? I can't take Rx painkillers because they make me feel much like I feel right now already...sick. Please help. It is Christmas and I don't want to end up in the ER. Thank you.
