I have a sore near my anus which keep on appearing and disappearing for the last 3 years now. with some time pus and blood. I ever went to hospital and i was given some medicine but the wound is still there. The doctor said it was a mere pimple but now i am getting scared that it could be something serious.Please advice me
Hi; Get examined by a surgeon what you are talking is probably called a fistula -in- ANO. You have had it since 3 yrs this long pimple don't last;please consult a surgeon he will treat you & if required he may remove it also.  Thanks
