I have a granuloma on my bottom eyelid on the left corner close to my duct

We do not have the benefit of examining you or even having a photograph of your issue.  However, a biopsy is appropriate assuming conservative measure such as a warm compress and antibiotic failed to resolve the issue.

Thank you for the question. You should inform your doctor of the problem. It could just be inflammation, but it could be an infection which requires treatment.Good luck,
