Hello,

         you ask if there is anything else they can do rather than a colonoscopy?, aside from having a stab at their best guess.Looks like they have done bloods and changed tablets so this is the next step.You really would not wish a blind doctor to operate on you, just as they could not see the extent of any problem without looking

              l have experienced several colonoscopies and each time l was so sedated l could not feel a thing or remember very much, and certainly no pain apart from the joy of having to flush my bowels before the examination.

                                      It helps you to be relaxed during the proceedure,and not overly stress which makes it a doddle.Balance that against the ongoing stress you are undoubtably going through not knowing the root cause of your current problems, and the fact that this could lead to a definitive diagnosis and early resolution.

                                              As with all things in life the fear of the unknown is always far worse than the actual reality.Please go ahead and have the examination,l was diagnosed with stage 3 bowel cancer that subsequently spread to the liver,and l am here today six years later leading a full active healthy life because l did.----- The only sign l had was loose bowels,no pain,not even tired but if l had put off having it investigated that would have changed very quickly thereafter.

                                                                                                    Good luck with the test and enjoy the food and drink afterwards,l know l did
