Blood on tissue after bowel movement?

So when I whipped I found fresh bright red blood on the tissue rather alot and drops down the toilet. I have gone back to the toilet without doing any bowel movements I just put tissue at the start of the anus and I still have bright blood around that area. It's rather sore around the opening sorry for the description. I do suffer from bad piles aswel. Does anyone know what this could be? My bowel movements was a normal colour?
