I had operated for piles in feb 2014. But still mucus and blood is discarging now. I had colonoscopy, endoscopy and MRI test after the surgery, but all reports are normal. My surgeon is confused to see this. He didnot found exact reasons of discharging. After discharge,  I feel itching and pain. And also feel that something is moving around anus I.e, leakeage but my inner clothes not get dirty. When I go for bowel movement, my anus area is too much dry and white pus collect on th face of anus area. Please help me if have any suggestions for this please
