I think I have Multiple Sclerosis. I can’t get tested because I don’t have health insurance. What can I do?

Is there anything I can do to alleviate symptoms? Any vitamins?

Symptoms include:
1. "Pins and needles" feeling- quite annoying
2. Constant equilibrium problems. I will sway lose balance simply standing and the other day, I fell on my face at work while trying to tie my shoe.
3. I lose track of my feet when descending stairs.
4. I’ve been tired and naps help.
5. I get random pains in my legs (usually although I had one along my hip bone a few minutes ago) that shoot through my body and make me stop what I’m doing b/c of the pain.
6. My eyes go in and out of focus and I’ve seen flashes of light.
7. My hands every now and then simply stop working. I’m a musician and I notice my left hand messes up on the guitar- simple chords that I know how to play.
