I haven't posted for a while. I do my own b12 injections once a week. For the past 6 months I've been having stomach problems- mostly pain. It's complicated because I have a condition called hereditary angioedema, and my usual treatment was stopped 6 months ago! However, in between "attacks" (basically my stomach swells up, you can Google it if anyone's interested) I still have problems. I have to eat a very bland diet and previously I could eat anything. I used to take a low dose of lansoprazole, 15mg every other day, now it's 30mg daily (this is so I can eat!). So my question is, if I increased my b12 shots, could that potentially help any stomach issues? I have had a recent negative test for h-pylori. I had a CT scan 2 weeks ago and get result tomorrow. It feels like a chronic gastritis and maybe a little ulcer that is not getting very bad because of the PPI. But otherwise I have no idea and am fed up. I don't have PA (negative on both tests, IF and the other one).
