For about 3 weeks my left leg behind the knee has been bothering me. Aching, hurting. Last Monday it became really bad, my thigh was sore, and had tingly things in my legs. I can't describe it any better. Tuesday my right leg was like this as well. Both legs are weak and feel tight and sore. Both feet are really cold and tingle off and on. Wednesday night my arms began feeling achy, as well as my upper neck and lower back. Today the legs are a bit better.

I went to the dr. on Mon., she sent me for pelvic x-rays which showed nothing.
Went back Fri., she took blood and is doing a whole panel of testing.

For the past maybe 2 years off and on I have this same feeling in my right arm. It'll last for a few weeks and then just vanish. For the same amount of time I've been having vertigo, like literally everything spins. So bad I have to pull off the road when driving. I also get very dizzy and motion sick when I haven't been moving, so there'd be no reason for me to feel that way. It'll last for a week or so then go away.

Also, this might sound stupid, but for about 2 years I have these bright electric blue dots that appear in my vision from time to time. Sometimes they're yellow, but mostly blue. I never told the eye doc b/c I thought he'd think I was nuts.

I'm going to request an MRI next week when I see dr. again. My great-grandfather had MS and I'm worried! Any advice?
