Please consider changing doctors. I had been on medical literature for many years that PPI,'s should only be used on a temporary short term basis. BTW, have you ever been tested for celiac disease. Requires an endoscopy and blood tests, which should include (if you have a really good gastroenterologist.) I was told for years that I had GERD and was put on a PPI for a number of years. He retired and I got a much younger gastroenterologist. He immediately started weaning me off PPI and scheduled me for an endoscopy. Turns out I had celiac disease. Do some research on celiac on this site. You may indeed have something other than celiac but it is often misdiagnosed in adults.
By the way, I have PN in both feet and legs, to just above the knees. There is a link between celiac and neuropathy as well. Mayo main website also has lots of info on issues re: PPIs.
