Hi I just got my surgery February 24th. The gas has passed and I thought that would be the worst of my pain.. When I sip on Water I get these sort of stomach cramps or contractions? They are very uncomfortable and I want to know if this is normal.. I also feel shortness of breath sometimes. Also, I'm very confused on how often I should be sipping on water and how much when I do sip. Every time I sip I have to burp :/ Kind of regretting my decision to have this surgery.
