Hi, I have been suffering from constipation and have been getting headaches every single day for the past six months now. I had seen a doctor and I was advised to take both enemas, and laxatives which did help at first but now I know I can't go #2 naturally. It's gotten to the point that I don't go for days and when I do I have horrible cramps. I have switched doctors and have been gotten many tests and blood work done and I was told my liver enzymes were too elevated, a few weeks after I got retested and even had an ultrasound and everything was fine. But my headaches persist, they have affected me emotionally, socially, because they get worse when i'm in public. I have a appointment for this Thursday to see a gastroentologist what should I expect? Should I take a laxative the night before ?? any feedback would be great..
