Sorry to hear about your situation snappydad.
I went through a similar journey. Minor tbi resulting in dizziness and nausea. Work related and workmens comp doctors told me to keep working, it will get better.
It got worse, not better. Denied disability. Took over a year to feel normal again. I was an IT engineer. Worse time of my life. That was 8 years ago. I'm very susceptible to reinjury to this day.
If I had to do it again I would NOT work through it. I would rest until better.
