I was told by the specialist that he was 95% certain I had IBS but that to confirm for certain he would need to do further testing I.e the camera. I decided as he was so sure it was IBS not to go through the tests. But now I am considering it, as I feel I am getting worse not better. But I am nervous, what is involved in the testing process and what other tests do they do other than the camera? Has anyone else been through this?
