Hi Pam,
How are you? I have missed hearing from you. I have been posting on the old brain talk with VicC and the old gang. Sorry to hear that you are going through this. I have had many problems with my teeth due to meds, I believe. I did have a root canal, and when I got the numbing injection, I think he hit a nerve, cause I just about went through the roof. I though I'd never survive that, but I did! Also holding my mouth open for so was was incredibly difficult and painful due to a previous surgery that I had. (you know....)But, I did not have any residual pain. I do think that the pain I experienced, was way out of proportion for that surgery. I will give you a ring if I still have the correct number. I am still using my HBO Chamber with great results. Hope you are doing well. Love Di
