i have been suffering from the same excessive trapped gas , and constant flatulence symptoms for about 2 yrs. The conditions have destroyed my social life, i'm to the point where i just stay home because i dont want to misconvenience other people. My gassy ora makes people rub there nose,cough, and complain of head-aches. Ive been searching on the internet for some relevance, but my symptoms are so common to several ailments and diseases. it seems like theres a constant build-up of gas ,soon as some is expelled my stomach fills right back up with gas. Sometimes it seems hard to expelgas even with a great urge to do so, and i think be it may be because the air being passed through is so excessive that it transforms to a gassy , sticky, green mucous which is not easily expelled because of its thick sticky texture. When ever i sit next to someone , they are so discomforted, but cant really understand why. Please does anyone have any suggestions
