Is it possible to have some auto-immune inflammatory disorder mainly in one eye?

[Yzhfd]

My left eye lacrimal gland started hurting extremely much suddenly, and has been hurting ever since.. Only in my left eye though, before both eyes were similarly bad but something made the left eye significantly worse.

This is the worst pain I've ever been in, constant aching in my left lacrimal gland, what could it be? Doctors don't think it's an infection because there is not very much stickyness.

I feel like whatever it is it is ravaging my gland, there has been much increased dryness in the left eye.

So what do you think guys?
