3 Mos Sleeve Narrowing?!?

[ThisTimeIsIt 71]

So I went in for my 3 mos checkup on Friday had hiatial hernia repair with sleeve and now i am having major acid burn and reflux and some minor pain so they had me do a barium swallow and the dr says it appears my sleeve is narrowing? Wth? Gives me a new medicine to take which i find out my ins company won't cover - so now I'm waiting for a new prescription to be called in and may have to do an endoscopy on aug 10th so they can check out my stomach - just when I thought I was finally on the upside and figuring out how to feed my sleeve this happens! Really hoping come the 10th it's all good at my follow up and I don't have any major complications - stressing myself out thinking if everything that might be wrong or can go wring if they have to stretch my sleeve - but hoping new Meds will do the trick once I can get them.

Anyone else have something like this happen?
