I had my sleeve on the 8th and yes, everything I drink (broth, Water, crystal light, lemon water, etc...) hurts my belly. It's kind of like gas pains but a combination of that with chest pain, and some other stuff all mixed in. So it's pretty normal at first. I'm 9 days out and it's gotten better.
Don't be afraid to bug the heck out of your surgeon. I do for every thing that really concerns me. Send an email, text, call.... whatever works. You'd rather be safe than sorry.
