Laser surgery is not 100% cure, it has it’s own problem. I think fistula has blocked. I suggest to get MRI anus and show the reports to me at my hospital at the earliest. Don’t think you should wait and watch, please don’t use any pain killers, as it can cause

Next Steps
MRI or USG to know how the track is formed, so that he can undergo fistulectomy at the earliest.
