Over the past year, I was in a third world country. I experienced a sinus infection that turned into bronchitas and I took antibiotics. Then I had a gum infection that turned into Tori and I took antibacteria mouth wash and antibiotics. Now I experience gagging when I eat, heart palpitations, anxiety, constant throbbing in my right upper quadrant, and headaches. Can bacteria do all this to someone and not show up in testing? Or what testing should be done to find out?
