How do I know if Fistula is cured? I had a kshar-sutra placed back in April and the last thread removed  in August. The wound has completely healed and even though there was a slight pus discharge until November but it's no longer there. However, I still feel some pain in the surgery area when I press it or sit down for longer hours. I have read a lot about fistula reccurence and can't go through all that pain and trauma again. Is there a way to know If my Fistula has completely cured or not? Is there a test that can be taken? Also, apart from maintaining a healthy diet what other measures can I take to make sure this doesn't happen again?
