I fully understand stand how scared you are, I was having stomach ache and blood in my stools, so knew something was not right, I contacted my Dr , she examined me and was sent a stool test through the post, the hospital contacted me and I received an appointment for a Colonoscopy, the night before I had to drink a sachet of Mango flavoured mix, and then drink a pint of water , the next morning another sachet of flavoured water (more like drinking a pint of salt water) by this time what I was passing was like having a pee through my bottom . My appointment at 1 ( 28th April) by that time I was so thirsty. The nurses were so kind , I decided to have gas and air, but didn’t really need it, I watched the procedure and honestly in my case felt no pain. They removed two small polyps and a much larger one. Still no pain. I am awaiting the results, but the dr and nurses didn’t seem unduly worried about them, so fingers crossed my results are clear. On returning home, still no pain, was glad to have a drink and biscuits. Please try not to worry about the Colonoscopy it was nothing to be worried about.
