I have a long history of inner ear issues since I was a teenager. I've only had one occurrence with vertigo about two years ago. I immediately went to my ENT to have it documented and diagnosed.
If you find a good AME, they can help you through the process. If it is a one time issue, it isn't a huge deal to get/keep your medical. Get checked out and have it well documented by a ENT. Don't just see your family doctor; your AME will not likely accept his work. I was issued my first class without any issues. The AME took copies of my medical records and tested my hearing (really just to show he looked at everything). He sent everything off to OKC and they cleared my medical without a second look. If you are having continuous issues, you will likely have a problem, as you (unfortunately) should.
As for your work and disability, I don't have a clue. I'm not flying for a career. I'm flying as a CFI as a side gig.
I wish you the best of luck.
