New to this, how can you differentiate Long Covid from MS?

It’s been about two weeks since my symptoms developed. Just to clarify what I’ve experienced so far is:

-Brain fog -Stumbling -Hot flashes even though it’s cool where i am -Palpitations -Dulled sense of feeling on left half of my body (not totally numb but i can tell it’s just not the same) -Fatigue -Trouble finding the right words to say -Sinus pressure

-Diarrhea

I told my primary care provider this and he told me to see a neurologist. This is where my question comes in. The symptoms for this are almost identical as MS and both are hard to diagnose. So how can i tell which is which? I was infected once during the initial pandemic (asymptomatic) and once a year or two later (symptomatic). I also got my two initial vaccine shots but never got the boosters. Truthfully, I’m really scared it’s MS and would prefer to be able to say it was just long covid but please be honest with me.
