I have had ibs for years and piles. I don't currently have piles but a very occasional streak of bright red blood on tissue or on the stool but more so dark brownish almost red mucus. I also have skin tags. I had a colonoscopy 2 years ago and an occult test and was given the all clear. The mucus has never bothered me but the change of colour has made me worry a little. I've normally had clearish to light brown. Is this something others have experienced? I'm trying not to worry but it's very hard as you h.a. sufferers know!
