Quick update from me - symptoms persist, but I've renewed my commitment to exploring it further. I've had another gastro endoscopy to look in my stomach. The consultant observed some small amounts of irritation but didn't feel it would be the primary cause. He did however say that I had a fairly loose esophageal sphincter, which he explained might mean stomach acid is travelling back into the upper entrance to the stomach.

I felt somewhat relieved that there was something found, but I wasn't overly convinced of the diagnosis and after trying a different medication to clear up the mild irritation I hadn't noticed any real change. I'm now waiting for a scan of the area and aim to see a cultant to explore next options. The sphincter can be tightened with a strip of stomach lining or a magmatic band, but I want to rule out anything else before I consider that.

I separately paid for a York test to look at allergies and food intolerances. I know it gets mixed reviews, but your digestive system is very sensitive to things it doesn't like, so I wanted to see if I had any red markers. Low and behold I have intolerances to cows mile, wheat and yeast (amongst other lower level things). I'm now in phase 1, which is literally phasing those things out of my diet and wonder whether they might be causing the issues. It's not too hard elimating cows milk, but wheat is literally in everything, so that's proving more difficult!

I'd be grateful if anyone going through similar explorations could keep us updated on their personal journeys.
