I'm having this weird issue where my burp just gets stuck halfway, and I've been burping a lot lately. On top of that, I've got this burning feeling in my chest, and my nose feels super dry but blocked at the same time. It's really frustrating. I'm also experiencing dizziness and sometimes even a burning sensation in my feet. All of these symptoms started after I had COVID in 2021. I've had allergic rhinitis for over 5 years, but I've never dealt with GERD before. My upper endoscopy and colonoscopy came back normal, as did my ECG and echo. I'm really starting to feel desperate and kind of pathetic. Do you have any ideas on what could be going on with me?
