I've am been facing a problem from past 2 years.There was a lump popping out of the anus after passing stool it used to reduce spontaneously after defecation .Later with passing days it has increased its size and became like a hemisphere (6'o clock to 12'o clock)even now it reduces after a while or after standing soon after passing stool.The lump is huge inside the anal canal pressing the right side of the canal )|.There was blood in stool only once 2 years back, now there is no bleeding .But there is soreness sometimes after passing stool,itchyness is there .And troubles after sitting for a long period.I use to sitz bath often the lump seems to reduce its size merely but again it comes to original size.
