Has anyone had a problem with OO causing colon pain? I have tried for a long time to take OO for constipation but it is not working for me. Actually nothing has worked for me. Everytime I use it I end up with sick painful cramps. I tried eliminating everything today but the OO & bread which I've never had a problem with. After a few hours of taking it I had cramps again. This is very disappointing. Thanks for reading my post.
