Hello, I understand that you are in pain, and I know how it feels. Piles or hemorrhoids cause pain, bleeding and also constipation leading various infections in and around the anal canal. Since you have been suffering piles from long time ago even on taking medications you have no relief then it is time that you need to consult a general surgeon to get it evaluated surgically it is better and the only way to prevent it reccure once again. Thank you.
