<bot>: Hi.based from your description, it could be any of the following: a hemorrhoid, anal polyp, an abscess formation, fistula-in-ano, or a fissure. It is best if you consult with your doctor for medical and physical examination of the lesion. Diagnostics such as photocopy and rectal examination will also be done. Management (medical and/or surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
