Possible Multiple Sclerosis?

I am a 27 yo mother of 3. I have been having cramping in my feet for the past 2 months, as if I was walking barefoot on rocks. September 28th, I started nervously shaking on the left side of my body, that within a few days gradually got worse and turned into tremors. When I would go to walk, my left toes would curl under my foot it seemed, and I would have to walk on the outter left side of my foot. I called my doc because I went partially numb on the left side, still had some feeling, but not full feeling. I was then hospitalized and had numerous tests ran, MRI, CT, MRA and Spinal Tap. Which all came back normal, however I'm currently waiting for the results of the Spinal Tap. My shaking and tremors got worse, as to when I would go to stand up, my entire body would just "bounce". I literally couldn't stand still without shaking tremendously. I had bladder incontinence, and am still having constipation. My Neurologist at the hospital says possible MS. However, I went to get a 2nd opinion to another Neurologist, whom didn't even look at my tests, and made a diagnosis of ADD (because I quit college) and Migraines. The tremors have stopped and I am able to walk again without the help of a walker or wheelchair. Has Anyone else gone through these symptoms? Does this really sound like MS?
