4 days post op and I keep getting this weird hiccuping/burping sensation and it hurts my back and my tummy a little is this normal? It happens randomly throughout the day and isn't constant.

Sounds like gas pains so it is probably normal. I had lots of weird feelings (in my chest and back) from the gas for the first week.

6 months out and I still hiccup if I eat too fast. yes, the pain is normal probably gas.

I'm having the same weird pain, I'm 5 days post-op, it's like this rolling sensation that starts at the upper part of my stomach and goes all the way up to my throat, I'm hoping it goes away as I begin to get more normal foods in me.
