How to reduce swelling in throat/esophagus due to lpr?feels like omeprazole is making it worse.is this possible?should i start my ranitidine instead?

It shouldn't: Omeprazole is actually stronger than ranitidine, so in theory it should work better, not worse. In truth, there is probably no single "treatment" for LPR, but it is a combination of diet, exercise, and speech therapy. If you can, seek out a specialist in the area who takes a multifaceted approach. Read this: https://www.enttoday.org/article/experts-delve-treatment-options-laryngopharyngeal-reflux/
