One thing you might consider is colon hydrotherapy (a colonic). Most cities (large and small) have this available. They insert a tube in your butt and pump water in and out, which helps dissolve some of the fecal matter that has caked up on the colon walls over the years and also helps to get rid of any blockages. I was getting this done because of a Liver Flush I was doing, not becuase I thought I had any bowel or colon problems. However, I found out that I do in fact have colon/intestine problems. Most of the food coming out was undigested, which it shouldn't have been. Therefore my body isn't getting the proper nutrients it needs. Plus, I found that there was no movement (or peristalsis) of my colon/bowel, which again isn't normal or good. I think the health problems I have been having are related to these issues, which I didn't know before I had the colonic done. In my area it costs $65 for one session, but it has been worth it. The important thing for you is to see doctors until you figure out what is wrong. There is a solution out there, you just have to find it. Good luck.
