Colonoscopy - fissure?

[Showbel]

Hi all, what should I do?
I have a colonoscopy booked for a week's time for worsening IBS symptoms and pain in abdomen when going to the toilet. I've had these symptoms for over a year but was pregnant and they wanted to wait until I'd given birth.
I have developed severe constipation since giving birth 10 weeks ago, and have developed what I think is a fissure (severe pain, bleeding) worst pain I've ever felt in my life when going to the toilet.
I've had it for about 4 weeks and it's not getting better. I've not seen a gp because the only routine appointment they have available is middle of October.
I'm so scared about the colonoscopy because I'm worried I won't be able to tolerate it because of the pain from the fissure. I'm having it with sedation.
Has anyone else been in the same situation and can perhaps reassure me?
I don't know whether to reschedule it as I don't want to waste anyone's time.
Thanks

I had this - tell the Dr and they can put local anaesthethic onto the fissure - didnt feel it at all.

It's probably a pile op

Sorry not what you asked. But very common after pregnancy. Ask your Dr to check.

Thanks, can I ask did you do anything specific with the prep to stop the pain? I'm just imagining myself being in agony for hours after taking the prep and not being able to do anything about it is making me feel overwhelmed. Numbing cream doesn't seem to do anything for me atm, using Germaloid and I still get severe pain

DH had this. He had so much sedation, he didn’t feel a thing except when they went round corners. Luckily I was there for the debriefing as he didn’t hear any of that either.

They gave him 10mg of amitriptiline to send him off to sleep, because the pain stopped him sleeping and then he went to the toilet, which set the pain off again..,,

He also had a cream to apply. It’s made of the same stuff as angina sprays. It healed up in about 6 weeks.

Thanks for your messages, I had the flexi sig yesterday. In case anyone is wondering about this in future and reading this, they put numbing gel on the area and I didn't feel it at all.

I'm just wondering now - the results were normal (thankfully) but I'm just wondering, if I had piles she would've mentioned them in the report right? Or are they considered too minor to mention (as she didn't mention the fissure either?) No biopsies etc were taken.
I would've asked her at the time but I was too out of it (had sedation) and by the time I wanted to ask her she was with another patient.
