..... just an idea that may or may not work and I happened to mention it yesterday in a chat; many years ago before i got ibs-D, I had a problem not being able to evacuate colon and was also sore in area so had been sitting in a Sitz Bath of warm water - bowl on toilet with seat up - didnt use the tube etc., just used a jug to fill the Sitz bath with warm water... it was for soreness but low and behold, it relaxed my bowel/colon and feces came out..... and once after having barium enema for xrays at hospital I asked for bowl of warm water after and sat in it and same thing. Unfortuntely 2 things happened, because of female area the germs from feces I think gave me the UTI's in bladder, so had to stop - I sure miss those warm bottom-baths tho. Would it be worth a try to see if sitting in warm water would encourage colon to do its job... especially the male body as I dont think need to worry about bladder infections? Am curious to know if this would work for you....J.
