I feel very severe pain while passing the stools occasionally. Even though the stools are normal, and not hard, but still I experience pain. I feel pain inside the anal region. And I have self diagnosed the anal region for any fissure, but didn't found any. Whenever the pain is severe, it lasts upto 5 - 6 hours. I try to have as much as water and liquids as possible. Please suggest me what should I do now? And what should I start having in order to treat the pain from its roots.
