Constipation is common in many people with MS

Constipation is common in many people with MS. I have recently found a way of achieving bowel movements without straining. Perhaps it will work with others!
Whilst sitting on the toilet I move the top half of my body in a circular motion. For me anti-clockwise works best. The movement is not very fast, approximately 5 seconds for every circle. After one or two circles each successive circle produces results.
