oneday - Have you ever consulted an endocrinologist (gland/hormone doctor)? The pcos, acne, and extra hair growth all sound like some kind of hormone imbalance is going on here. A family doc will not be able to do the specialized testing necessary to nail down a hormone problem.
Also - have you ever had the pcos diagnosed surgically? I'm wondering if you may not have endometriosis causing the cysts - also known as "chocolate" cysts. If endo implants on bowels, it can cause the symptoms you describe. It won't show up on any tests either - has to be diagnosed surgically. Just a thought.
