and feces unless i do not massage down left side of "Splenic Flexure" and push feces towards rectum. had all blood and hormon tests. went to 8 doctor. had colonoscopy everything shows ok. no one can understand why i wait there feeling "full" and try to get rid of feces. straining doesnt work and it took two hours to get rid of "fleet soda".. It must be someting muscular
