Granulomatous Inflammation in Biopsy.

1) Fistulectomy done 34 days ago. 2) As per Fistulogram (MRI Report) it was Grade I simple intersphincteric peri-anal fistula at 6 'O Clock position of 3.2 cm long. 3) Biopsy Report says Granulomatous Inflammation. 4) I was on antibiotics for 5 days and pain killer for 3 days after my discharge from Hospital on the 3rd day from surgery. 5) Till now, I taking Sitz bath and applying a tropical ointment on the site locally regularly as directed in the follow up visit. BUT, I)  Draining has not stopped still now though rate is reduced to some extent. II)  Cannot sit comfortably till now because of mild pain in the fistula site. III) I am on leave for the last five weeks. IV) On follow up after two weeks doctor said, wound will heal, nothing to worry. Please Suggest. a) For Granulomatous Inflammation should I see any other doctor, as the treating doctor did not say anything about it.? I am very much worried about it. b) What should I do now? Should I join my duty?
