I recently found a lump (which may have 2 smaller pin sized lumps) right outside my anus. They are not itchy, but have increasing gotten more painful. Frankly before i noticed the lump while douching, i had no discomfort. I havenot had anal sex in over 4 months, although unprotected. I am very worried.
A lump in the region you have described could be a hematoma or thrombosis of external hemorrhoids or anal condyloid all of which can occur with anal intercourse. In some, they subside by increasing fiber in diet, but in others it requires medical or surgical therapy. You can visit a Surgeon or a proctologist.
