If it's not safe for you to drive--distraction from pain or meds, and driving with the wrong foot in an unmodified vehicle, anyone can report you to the DMV. I doubt it's out of spite and more a public safety concern. Seriously!

How long have you had RSD?

Getting a ride to work, sounds like a very good idea, btw. There is also sometimes public transport for the disabled available.

I think you'll have a better argument for keeping your job, if you stop trying to hide how you're attempting to cope one handed. Get your doc to write you accommodations that will allow you to work 8 hours on the clock, but with extra breaks where you clock out as needed. There are all types of adaptive equipment available.

What about inpatient Ketamine? If you've had a good experience with out patient, you might have a good chance for remission.
