This has happened a couple of time now. Today I passed a fairly large stool that seemed to be a healthy brown colour, no blood on it. Wiping, however, left a streak of blood on the toilet paper. The blood was bright red and therefore probably fresh. There was no pain passing the stool, but sometimes after I pass I feel a discomfort, or a slight burning sensation in my rectum.

Is this evidence of a fissure? I thought fissures were meant to cause pain when passing, so it concerns me that it's fairly painless. Anyone have experience of painless fissures, or discomfort following passing?
