Hi, my age is 27,male . I have irritation around my anus since i was 14. But i didn't paid much attention to it, as irritation remain for someday,and then vanish for months. For past 2-3 years i have noticed that there is projection around my anus tip.Generally irritation is there after 1or 2 month. After 2-3 days of irritation there is blood in the stool, which is most probably from the projection, and then irritation stops (for month or two).This is happening in regular cycle.What shoul i do
