I have really bad pain in my left side that radiates from the front to the back in  my groan and down to my left sheen. Sometimes the pain is so bad that it stop me in my tracks. I feel bloated and contipated a lot. One day the pain was between my shoulder blades so bad that I thought I was having a heart attach. I went to the ER and had a ct done. The results were I have two different spots in my colon that are thickening and somethin on the decending side. what do you think it can be? I am a 46 year old female and have had this going on for sometime now.
