dbpei,
I have not been tested for Lyme disease. With the increasing tooth pain & numbness - the way it radiates through my upper lip, the left side of my nose and into my left eye and ear, and increasing headaches, I am suspecting the root canal more and more. I have begun researching biological dentists in my area. Still have to rule out acoustic neuroma. I emailed my ear doctor and am waiting to see his thoughts on the possible connection to infection from the root canal.
Thanks for your response. I will definitely be checking back with any new info.
