I also hope you don't have the big C. Don't give up with your testing because honestly it is a hard cancer to find. I called a specialist at MD Anderson and they agreed it can be very difficult to diagnose. I have read story after story of this cancer being missed by scopes, CT scans and even pathology. So, please if you believe you have this cancer, please pursue further testing despite anyone's advice. I'm not crazy and the pain is real. Some people don't experience pain, but some have excruciating pain. Thanks and good luck to you.
