Please don't feel guilty or pathetic - it is nothing you have done. Some people are just unfortunate. 

I have colonoscopies every 2 years and mine tend to be very painful. I have just made it to the end of them all but only just. My other family members, but contrast, seem to find them easy and fall asleep during them! 

I find the medication has little effect on me too.

Then, after years of easy and straightforward colonoscopies, my sister had a really bad one and they couldn't get to the end of it. It was just bad luck- nothing anyone had done. I randomly had one easy-ish one last time - the doctor told me it can just vary on the day.

When my sister's colonoscopy wasn't completed they offered her a CT scan. I guess that depends on the reason for the colonoscopy (we have them due to family history).

I hope you've managed to have some rest and are feeling OK. 

Ah, thank you Applebee, you have really helped to reassure me that it's not my fault. You and your family have certainly been through a lot of colonoscopies, I do hope that you are all doing well.

I have managed to get some rest today and have no pain, thankfully. Hopefully I will be back on form again tomorrow. 

I was not expecting any problems at all, as three of my friends and family had told me that they pretty much sailed through their procedures, so it did come as a shock to me.

Now to wait and see what will happen next in these investigations! 

Thanks again for taking the time to reply  x
