I think its worth a note on my symptoms of this condition and Colour Blindness.
See I've always had a problem on the snooker table when it comes to red and brown. I have on numerous occasions potted the brown by mistake for the red. Both look the same to me unless I study them closely and compare one with the other. Obviously or not so obvious is the difficulty in spotting blood in faeces which for me I have not noticed. The only symptoms have been the very occasional messy / slimey bum wipe which led me to believe I had picked up an infection from one of the places that I eat and was being re-infected periodically. It was after about 3 months of this that made me visit the doctors however with no other symptoms I was lucky that my doctor gave me a referral.
