No, it's not a silly coincidence. I do have this, too. This happens to me esp. when my proctitis is flaring up and there is narrowing. In these days, I have d but can't have an easy bm which necessitates straining. When I get out of the bathroom, my two knees hurt me severely, they don't hold me and I'm about to fall down. I don't know what's the reason. My GI refuses this and told me that I can faint after vomiting but a bm this is not possible. I have suffered from this for years w/o an explanation. I once read that sometimes because of sitting for a long time the blood goes all down to the legs and that's why the brain does not have enough oxygen and one faints but I'm not quite sure whether this is right or not.
