hello, have problems with constipation, and yesterday, in the space of an hour i felt like i had diarrhea and went to the toilet over 5 times in an hour, then right through the night, i had discharge, even when i passed gas, and there was traces of blood in it. I also had discharge when i passed a stool. Never had this before. My dad has colon cancer and maybe i am just getting paranoid.

thanks
