ive been having this pain/tingling sensation in my lower abdomen. at first it was in the lower left side but now the feeling transferred to the right side. its weird cause like i can feel it moving around in there. sometimes it goes away but most of the time its there. this started happening after the day i was in the movie theater because i was holding in my fart throughout the whole movie. is this just trapped gas or is it something serious? the pain doesnt really hurt that bad at all it just bugs the **** out of me. also i noticed my bowel color turned like green or something not really sure cause im color blind but the color did get lighter. anyone help?
