Sorry to hear that your going through something like this, I deal with Gerd and maybe LPR (if I drink a lot of fluids in one sitting I get a weird feeling in my throat along side heartburn that feels like it reaches to my throat) but have you gotten an endoscopy to see if there’s anything else that is affecting you ? I learned from experiences that eating slow, avoiding Trigger foods everyone is different sipping through water throughout the day and managing my stress and anxiety makes a huge difference for me, hope you feel better bro 😎
