Hi. Thanks for your query. Noted your history of development of a knot inside of the anus about a month back, which popped up to release blood for a day and got healed up. Now there is development of more such knots and the whole area is purple, there is itching. This is most indicative of prolapsing piles/hemorrhoids. I would advise you the following: Consult a general Surgeon to have per-rectal examination as well as ano-proctoscopy followed by colonoscopy. This will give the exact diagnosis and if these are grade III piles, get operated as there is no medical treatment for such prolapsing piles. Take mild laxatives. Have sitz bath. Avoid food and beverages that have bad effect on digestion or motion.
