I had a colonoscopy yesterday, my first one ever. I did have the sedation, when you remain awake, but I don't think it worked, if it did then I hate to think what the pain would have been like without it!  The pain was horrendous!  I felt like my insides were being ripped out, I tried to perservere but couldn't and had to ask for it to be stopped. I read my colonoscopy notes which say 'tortuous colon', and 'very acute sigmoid descending junction'. Is this the reason why it was extremely painful?  Last night I had a lot of trapped wind which was painful in the upper part of the stomach, and this morning diarohea and burning in my throat. Is this normal?
