Spas- Please keep me up to date on your biofeedback! I am going to talk to my doc because I have the same problem sitting & straining all in effort to have a poo, then what comes out.... a little pebble - after all that straining! I have thought I was going to give myself an aneursim before from straining sooo hard and then still feeling as if I need to poo some more. It is a vicious cycle, man!
