Can any multiple sclerosis sufferers tell me what their *very first* symptoms were and which made them realize that something pretty serious was up?

Mine started one Saturday morning with a tingling in my gums in the left side of my face. During the day the tingling spread to my lips and I thought I might have developed some kind of sea food allergy, since I had crayfish the night before. two days later exactly half my face, including half my tongue was numb/pins and needles.

I went to the doctor on a Monday, she did some reflex tests and then referred me to a neurologist who saw me the next day. I actually never once thought it could be anything serious until the MRI results came back and my neurologist said he was 100% sure it was MS and that the lumbar puncture would only confirm it, which it did.

my initial symptoms were right side weakness and electrical like shocks that resonated through my body. then came a bout of optic neuritis and blind in my right eye when I woke up one day. then the constant fatigue and pain. an MRI showed lesions on my brain, an LP showed abnormalities in my spinal fluid and the ON confirmed the DX.
Here is hoping that you don't have it.
