Rectal Bleeding and Severe Aneamia

Hi. Please excuse the graphic detail in advance..

I've been suffering with extreme rectal bleeding for many months now ... (I have 1 or 2 days a week when I don't bleed)  but most days its Bad!! my bowel habits have changed from once in a morning , but now I can go between 6 and 15 times day. This is not just a smear of blood on the loo paper but a bright red massacre in and around the loo, plus blood clots! I never feel like I've emptied myself and most of the time I have a constant dragging/ache down there! In fact, I've bleeding that much I am suffering Severe Aneamia,  ( shown by blood test) which is causing more problems for me. Dizziness,forgetful and confusion. Extreme Fatigue. Hair falling out. Tingly skin etc. I had a Gastrocopy and colonoscopy in August. 

 It showed i have a hiatus hernia and grade 2 Osophagitus.  They took biopsy from my Colon but they came back clear.  I've had 2 lots of stool tests... 3 lots of Blood tests.  Rectal exam.

I took photos of my toilet visits because I felt like the docs were not believing me... the doc recoiled when I shown him all the blood and the clots. Now, I'm being referred back for a more detailed colonoscopy because my doc thinks that they haven't done a good enough job. I'm sick of it... it's making me feel poorly losing all this blood. Some days the blood actually pours from my bottom like water pouring from a tap!

Can any body help??? 

Did you ever figure out what it was?

I sure hope they can help. I came here to see if anyone experienced something similar after my last colonoscopy. They’ve injured a part of my anal area that seems like a piece of skin won’t stay inside there. They removed some skin for biopsies and I’ve had those bloody stools as well though not quite as bad, mine was in November. 

I’ve gone to three or four clinics now trying to figure out which Specialist works on that area. Hope you get better.
