This is driving me crazy

I've had LPR for many years but in the past few ive had straight up a burning sensation in the back of my mouth instead of the bad globus sensation I always had before. I've tried just about everything at this point and nothing seems to work well or at all.

In the past 3ish years ive had a clear edg and clear barium swallow xray. Tried to do the acid watchers diet and was very strict with it for 10 months and all it did was make me lose a bunch of weight. Unsure what to do now id appreciate any advice
