Hi & welcome,
I don't know how you feel about chiropractic, so I'll add some info links below.
I had dizzy/vertigo on and off with my RSI injury, which became TOS, and I happened to come across a very good DC, that was able to help many of my symptoms.
As a kid I had gotten bucked off my horse and landed on my head, plus some minor car accidents{hit head again} , sport injuries etc.
That's why I began looking into chiropractic for treatment and found the info about c1/c2 {atlas/axis} adjustments.

Chiropractic care info- a good one can help with many symptoms:
