does anyone know why this is happeneing?

I have the same issue...

I have irriatated my band after a double pb the other day.

This is day 2 of liquids for me.

Yesterday was tea, broth and a popsicle

Today is tea, and 2 popsicles so far

I am slowwwwly sipping to keep hydated because the liquids came up yesterday.

I am gurgling less...burping more...

do not feel 1 bit of hunger, just feel like I need to proceed with caution... kinda swollen, bruised like I scraped my insides feeling.

The configuration of your stomach is altered. It isn't one nice big bag any more. That's one reason some docs say "no straws" (although once I was 6 months out I started using mine...gum disease...but don't notice more/less burping)

It will get better over time and you'll get used to it but things are not like they were in there; you'll burp and gurgle more and some foods will produce more gas than you are used to.

This is also a big reason we're to avoid carbonation...something carbonated in the little pouch...or trying to escape through the smaller opening in the stomach, can be a recipe for pain at the least.

Hang in there!

And yes if you had a bad PB (esp at just 2 months out) it is good to let things calm down before you go back to "normal"
