A urologist is a doctor yes and should know what a fissure is through basic med training however they specialise in everything on the front half. Reproduction, urine, renal. They won't look up your bum to diagnose a fissure as it's not their area of practice. They probably don't even stock anal speculums! They would most likely sympathise and refer you on to a colorectal specialist.

It's the same as having a fissure being under the care of a colorectal consultant and you come down with urinary problems - they wouldn't be able to diagnose and would refer you to a urologist. When it comes to these problems it's so important to get the right diagnosis and treatment and that's only something a trained specialist can provide - I know it's a bother but in the long run it will be worth it I promise.

So I look for a colorectal specialist?

I would definitely recommend seeing a doctor and ask them to refer you to a specialist. Yes you might not want to be examined but it might be something more serious and by ignoring or treating it as an AF could make things worse.

I have suffered from AF's for 2-3years and have never had that much blood before but everyone is different. Definitely bite the bullet and go see your GP. You could have internal haemmorhoids as they bleed like that and they're treated differently to AF's.

Surely your urologist or oncologist can refer you to a colorectal surgeon. Please don't put it off, or be afraid. You apparently have a history of cancer, and I'm certain your oncologist would want a colorectal specialist to look at you. Again, please don't be afraid. The MOST likely explanation is hemorrhoids, or fissures, which could be caused by any cancer drugs that give you constipation or diarrhoea. But - get it looked at.

I bleed quite regularly and had all sorts of tests done to be told that it's my internal hemorrhoids. I stopped worrying about it in the end. I still have blood, very similar to your pics, and sometimes worse. Clots not so many these days. Usually if I have more blood (red as yours!), I have not "finished", so I sit myself on my Sitz bath over the loo, bum in warm water, til I feel the need to go. After I have gone, no blood. Hope my saga helps!

It's not a fissure, it's a fistula. The blood and pus were actually coming out of a different hole about an inch or two away from the anus. This hole is near the area that the pilonidal cyst usually grows, but closer to the anus.

I saw a CRS and have surgery scheduled for Wednesday. Horrible...

Glad you went to see someone and its best to get it sorted out sooner rather than later

Good luck

Okay this is what's happening to me! I had the surgery, but it's been more than 5 months. It randomally started bleeding like that yesterday and today! I have no pain ( thank God) but im really concerned! I hope you feel better.
