<s>[INST] 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? [/INST] Hello, Thank you for your contact to Chat Doctor. I understand your concern. If I am your doctor I suggest you that all such things can be possible with septicemia or once the bacteria circulate in the blood. I advise you to undergo blood culture and sensitivity testing. Take treatment according to sensitive Chat Doctor.  Also check for if you have any allergy or something like that. There is also a possibility of allergic sinusitis or fungal sinusitis in you. Kindly test for it also. I will be happy to answer your further concerned can contact me. Chat Doctor. Infectious disease specialist. Thank you. </s>
