I haven't been diagnosed and am somewhat new to all this, but my right leg collapsed on me when I tried getting about of bed about a month ago. I could move it around just fine when I tried to stand it was like it wasn't even there and I fell. I tried again, same thing happened. The third time it was okay. It was so strange and I panicked. I just figured I had slept on it weird and it was seriously asleep or something but there wasn't any tingling or pain. I never thought to associate it with MS. Is that even a typical symptom? Like I said I have had some symptoms, but when I had my MRI and blood work done a couple yrs ago they were clear.

I'm sorry I cant offer advice, but just letting you know a similar situation happened to me too!
