Over the last couple of weeks I have been having strange gurgling, and popping from my left side just above my hip. Its really uncomfortable and embarrassing as it sounds like I am passing wind. Its like explosions inside rather than out! Its really quite noisy and feels like I need to be stuck with a pin. Is this trapped wind and why is it only ever on one side, feels like something blocked! I have tried windeze tablets for trapped wind but it doesn't help. Can anyone offer advice on this gross embarrassing prblem?
