3 Years post LINX

I am 3 years post LINX. The first year was great and I was off PPI's (although I had some swallowing difficulties and a couple of extreme incidents). The swallowing issues are almost gone, and I've learned to take smaller bites and always have some water ready while I eat, in case the food gets stuck and doesn't go down. I still can't vomit and I can hardly belch. But MOST importantly, over the past 2 years, I've had stomach pain that comes every night and usually disappears shortly after I wake up and get out of bed. I've had 2 endoscopies since and they've told me I don't have any relux and the device is working fine, however the stomach pain gets extreme some nights and wakes me from sleep. I've tried going on PPI's and that hasn't helped. Was wondering if anyone has a similar experience...

Thanks for your reply. Yes, I have used pepsid, PPI's (so many different ones), and other acid reducers such as tums and malox (and I've used them over an extended amount of time). Nothing seems to work, I'm wondering if it's physical pain somehow exerted by the device.
