I get this from time to time...otherwise I just have flatulence and pain which is bearable...when it is really bad the pain is terrible and I cannot rid myself of it with any amount of antacids etc. The only thing that really helped was a 2mgm Valium which the Dr prescribes for emergencies! I think the fact that the valium relaxes the muscles allows the flatulence to start moving on its way! So sorry, cos I know how sore it is and as I had this after a social meal/gathering I know how it can be unbearable,....had to go home as it was too painful to talk and I couldn't think of anything but the pain!
