Im not sure if its trapped wind or not but the other night it felt like my tummy was about to explode and its been on and off since then but it feel like bubbling/moving around and i have never had this before at all?
If it has been going on for a couple of days and is painful I really would suggest phoning up NHS Direct, its just that none of us on here are Dr's (sorry if you are) and surely that would set your mind at rest?? Hope you are feeling better soon.
