I under went fistulectomy surgery on June 1st 2017 .wound has been healing but puss is still coming from the wound. Doctor told ki I need to under go Mri pelvis scaning again. As only doctor could identify end tract but he couldn't find opening tract. He told like I need to under go another surgery if opening tract is found. I'm really worried about this. Pls guide me about my situation. I don't have any pain. Only puss coming.
