I have been having a lot of medical problems here lately to include swollen abdomin and pain. 8 month ago I was hospitalized for an addison's crisis and they said that I had free fluid in my pelvic region that look like a cyst had burst. Now the pain is back and lots of swelling. I had a ct scan done and the doc. called to day and said he needed to see me back. He said that my unterus was retroflexed and was pressing on my colon causing constipation. I don't think I have been constipated. And I have googled this all day to no avail? What causes your uterus to colide with your colon that way, and what do they do about it?
