Sorry to hear that.
That's a very quick diagnosis of MS. Sometimes it can take years to identify and diagnose. So many auto immune diseases, lupus, ms, mg, etc all have very similar symptoms. I've been going through it with my GF for years. Probably doesn't seem like it....but if you do have MS it's better to know sooner than later and get moving on a treatment plan.
Having MS 20 years ago was much different than today. Treatment, mitigation, and prognosis have come a very long way. It can be managed so much better with way less impact.
Tip - If you are still dealing with the Vertigo, try a CBD vape. My GF dealt with Vertigo for months, sometimes for 2-3-4 hours without a break. The Vertigo meds didn't do a damn thing, but CBD or marijuana would stop the Vertigo in seconds...literally seconds.
