That stuff you mentioned about brain fog, headaches and muscle pain - I have that. I sleep hours longer than I used to and still feel tired all the time. I feel weak and just lousy. That dentist also put me on an Antibiotic (a cephalosporin) for 2 MONTHS and it totally screwed up my body. I was so hormonally ouit of balance that I didn't even have a monthly cycle for two more months after the Antibiotics stopped! Not to mention I started developing all sorts of secondary antibiotic-related infections from the medicine killing too much good bacteria. No change in that tooth pain for all I went through, however.
I feel like an abused lab rat. My dentist referred me to an endodontist again today (who happens, haha, to be his brother). I think I am going to go to a specialist in Cleveland for an implant consult and have this awful monstrosity yanked out of my head once and for all. I have a family to care for, I can't take this.
