I am worried that I might have multiple sclerosis, does anyone have any advice?

I have symptoms of MS and I don't want to jump to conclusions, but I know something isn't right. For about the past year or so, I have been dealing with on and off problems of dizziness and fatigue. More recently I have noticed my hands becoming weaker and my hands shake when I hold stuff, like a jar of peanut butter. I also have been getting muscle twitches everywhere, from my face to my stomach to my legs and arms. I have also seen a massive increase in my sensitivity to motion sickness. Just being in a car for 10 to 15 min can sometimes make me nauseous, but not every time. Then there were also the sever aches behind my eyes, like migraines. I am afraid that I might have multiple sclerosis, but I have heard other people tell me that stress and anxiety can do the same things. The reason I am worried about MS is because I read that it can be triggered by a virus or infection and these symptoms started arising shortly after I had some kind of really bad flu or food poisoning of some type that landed me in the hospital. Then again, that is also when my husband was deployed, so there was a stress factor then as well. I am just worried and any advice or help would be amazing. Thank you.
