stool pebbles

stool comes out in pebble/ball form versus banana shaped and smooth. other symptoms are occasional pain with bowel movement in rectal area and stomach, bloating, no problem producing bowel movement aftr every meal. in fact bowel movements are pretty regular but the stool consistency is what concerns me. i also feel a slight bulge in lower right abdomen. no pain but its like something is there and when i push by abdomen out, i can feel it. i sometimes wonder if my colon is bunched/knotted up. i dont have any pain accept occasional rectal spasm that last 1 second but are sometimes very sharp. i wake up in the morning with slightly inflamed fingers but feet are fine. i eat a lot of green veg, rarely eat meat, occasional ice cream, i love bananas fruits and veggies. please tell what your thoughts are about what this condition might be and how to remedy it. one more thing, i had colon hydrotherapy on 7/14 and eliminated a lot of waste however after 48 hours of having regular meals, i was not eliminating at all. by end of 2nd day following colonics, i drank tea with senna herb and it got me going again but i am no longer as regular as i was prior to colonics. im wondering if my colon has stretched out over time, slowing down digestion and causing constipation. Please tell me your thoughts based on my synopsis and recommend a remedy, Thanks you!
