How to know ?

Hi guys so earlier I went to sleep and I tend to sleep in weird positions which always cause my hands and stuff to fall asleep or I have marks when I wake up so I went to sleep on my arm earlier and its felt kinda weird ever since like shaky or like I have to move it I don’t really know then I searched up like what it could mean since I’m a freshman in highschool I tend to use google a lot and it said that I could have something called MS and that it can’t be cured I’ve read all the symptoms and I haven’t had any vision problems or anything just muscle spasms everywhere I tend to have them a lot it’s just the right arm feels weird when I think about it but when I don’t pay my arm any mind it doesn’t feel weird anymore but it’s literally only my right arm so idk if I have it or not but then kinda in my other arm so idk maybe I’m panicking
