Perianal abscess 12 o clock position.

Hello doctors, I'm a 31-year-old male. Two weeks ago, I had a small lump at the 12 o'clock position, just above the anal opening (between anus and penis). It was painful to touch but no fever or sitting discomfort. A general surgeon advised an MRI Fistulogram, which showed a tiny 5.6 mm perianal abscess, no fistula, no anal canal communication, and no tract formation. He vaguely said, “whatever the report, continue antibiotics” for 5 days. After completing the course, the pain is gone, the lump is smaller, and when I pressed it, a small hard white pimple-like substance came out. Still the surgeon insists on laser surgery without any post-report consultation or explanation only said he’ll process cashless approval. My questions: 1. Is surgery really required now? 2. Can this heal fully on its own? 3. Will it become a fistula later? 4.Are sitz baths  required Mri report attached for your reference
