Fred must have sent you to McCown who definitely has a lot of experience with oral pathology. I've seen him before but would not see him for anything else except that.
Detoxing after major oral surgery is a slow process, can take years. But it's really important. I had gold crowns with mercury fillings replace and I got SO sick with cold symptoms for a month. It's been over a year and I still get symptoms of toxin poisoning. I'm still detoxing hoping it'll improve over time.
I'd highly recommend seeing Dr. Wendell Robertson in Spanish Fork, UT for followup. He works closely with Fred and he's SO good. My family flies from east coast every year to see him.
Did you talk to Fred about your symptoms? He has info about detoxing and cleansing.
Did you ask Fred about other dentists besides McCown?
