I had my second colonoscopy in July, my first being 3 years ago.  My first procedure was fine, hardly any pain, and what bit was experienced was relieved by releasing some of the air they pump into you, and "trumping it out."  Was happy to tell,people that there was nothing to it, and not to worry.   Then I had my second procedure, and the difference in experiences was staggering.  This time I had sedation that did not work, absolutely nothing in relaxation.  The pain kicked in almost straight  away, and I had Entonox pushed into my mouth.  It didn't help me during childbirth and it certainly didn't help me during this procedure.  The experience was horrific, and would certainly think twice about having it done.  I filled in a questionnaire ten days go, where I added my comments about the procedure, one of which was that after 5 weeks, I had not received my test results on the polyps they removed.  Tonight I got a call from the hospital saying that they had it recorded that someone hd spoken to me on the 22nd July.  This was not the case, but I felt that I wasn't believed.  In the end I asked for my results to be read over the phone, and was told that one polyp was benign and that the other was one of the polyps was one of those that could turn cancerous, but was not cancerous at this time.  I have since done a screen shot of my calls list on my phone, to prove that nobody from the hospital contacted my from the 15th July until tonight.  I cannot seem to get an explanation from anyone as to why the procedure was so different from the one I had 3 years ago, and as for why I suffered such pain was that it could be age, or that my bowel spasmed.  They really need to take a good long look at the way they deal with their patients.
