I've been having stomach pains, with a lot of gas pains, for over a year. They come and go. Lately (last week) I discovered a "lump(?)" that I believe is waste in my ascending colon. It won't pass through. I can move it down and feel, hear, waste getting past. I think it's waste because I can move it. But I can't get it to dissolve or soften up so it will pass through. I've increased my fiber intake and am drinking lots of water. Any ideas on what else to do?
