Why does my left side of my body feel weaker than my right side? from my eye to my jaw, my arm and my leg. Sometimes i fell my left side of face and arm get a little numbed and a little pain on my arm and leg. I have gone to the er thinking it might have been symptoms of a stroke but they advised me to see a neurologist. I had an MRI, an EMG and other tests done. Everything came out negative. I feel my symptoms getting worse. I had one episode where i woke up to use the bathroom and collapsed because my left leg felt paralyze. It only lasted seconds though. Im going to another neurologist in a week for a second opinion. Im a 35 yr old woman and scared. What do you think might be causing this?
