Anyone have any info on these? I think that is what it is. It crops up unannounced and suddenly and seemingly without provocation; goes away in the same manner. But while it is acting up, it has been bleeding profusely, lots of bright red blood that soaks toiletpaper and drips into the toilet and makes the water quite red. Doesn't hurt at all, and stops bleeding as soon as I'm off the toilet, only bleeding while I'm sitting there. What looks like clots on the tp too, maybe just a thick amount of blood. Any info appreciated!
