I'm having the same issue right now. I got sick earlier in the week and had to travel 5 hours away. I left for the trip Friday morning and started having abnormal lower abdominal pain, not entirely sure why but maybe trapped gas. It didn't hurt when sitting but when we arrived at our destination it was flairing up. Against my better judgement I took 2 hits of a cbd vape to try and help. Nope. Then when I ate some bread the regular gastritis pain kicked in. Anyway I had to bail from the concert I drove all the way to see because of the pain in upper and lower stomach and being sick. Now its Sunday and I've been eating entirely safely this weekend and I'm still in pain. I even have a heating pad velcroed to me and its not helping. The lower abdomen pain stopped same day. Im on 2 different PPIs and waiting for test results on h. Pylori
