When you e-mail me, my reply goes to your e-mail account that you listed with CureZone. :)
I think you need to see a special doctor for this issue, especially if it's constant.
When it is difficult to pass a stool, that usually means that you are sitting in a bad position. The natural position is crouching down. Nature didn't make our bodies to sit in a chair or on a toilet! :) So you need to adjust your bathroom so you are crouching rather than sitting. You can put something next to the toilet to put your feet on, or use a portable potty on the ground.
