I usually do not have epigastric stomach pain but stomach is "sensitive" when I eat acids (fruits) and I get nausea when I eat protein (meat or eggs) or tannins (teas/herbs), but I also have lack of digestive enzymes. I also have silent acid reflex - sore throat and losing voice for more than a year and even my teeth started hurting recently from the acid spills overnight.
I started the eradication regimen yesterday and my throat and voice instantly improved with the first dose of antibiotics. Teeth stopped hurting too. No nausea yesterday but I am also not eating proteins because I am taking PPI every 6 hours.
If they are not going to do resistance testing on your H. Pylori, you can immediately start the Bismuth subcitrate. It should alleviate your symptoms. I test-drived it for a month before starting the antibiotics.
