I had Nissen Fundoplication surgery a year and a half ago. I have had no serious side effects and healed well, but ever since the surgery, I make really loud squeaking "hiccup" noises whenever I have air in my gut. I can burp, though not as normally as I used to. The squeaks don't hurt, but they are very loud and can be embarrassing, though some people claim they're cute. Does anyone else have these? I've never heard of anyone becoming "squeaky" after the surgery, and I'm beginning to wonder if they're actually a side effect of something else.
