hi I’m really concerned I’m getting anal pus out of my rectum when I feel to need to pass wind I can feel it it’s like watery blood mucus. Just wondering if any one else gets this  I seem to get it on and off but I feel really worried  I’m having a colonoscopy after the christmass holidays. I’ve also had a rectal examination doctor said she couldn’t feel any thing up there  but this symptoms have appeared a bit after that  feeling scared I have anal or bowel cancer  could this still be internal piles that the doctor couldn’t feel  would really appreciate if some one as experienced same thing to reply I suffer with anxiety and stress please help
