I was dx'd with MS over 5 years ago. For the last two years I've suffered with severe constipation. It got to the point where I couldn't go w/o a laxative.
I was seeing a GI doctor who just wanted to keep trying different meds, which weren't working. So right before an appt with him I had a painful 24 hours. So I called his nurse and left her a message saying that if doctor So and So wasn't going to refer me to a surgeon then going to my appt would be a waste of his time and mine.
The nurse called me back and said she would have the doctor call me. He called me that evening and referred me to a surgeon.
The surgeon did some tests, one being a sitz marker study. You swallow a pill that has 24 tiny 'markers' in it. Then you go in for xrays over the course of 5 days. On the 5th day the xray showed I had 23 out of the 24 markers still left in my colon.
I had my colon removed Oct 07. I can now eat and go to the bathroom regularly.
