Muscle Twitching/Calf Pain

Hello, thanks for taking time to read this. I am a 40 y/o man who has been, for the most part, healthly my whole life. That is until this May (2011). I was very busy at the time (coaching my son's tee ball team, work, dealing with a vacant rental house, etc.) I started having calf pains and twitches at first and then it spread to my entire body. A twitch here and a twitch there. I went to my PCP and he did the normal blood work, even testing for tick bites. At one point they even checked for blockage in my legs. He soon sent me to a Neuorologist. I had two EMGs, MRI of the spine and brain, lumbar puncture,  and other blood tests. The MRI done on July 14 showed a spot on the spinal column, a second MRI was ordered and done on July 29. The results were that the spot had gotten much smaller and the diagnosis is that I am healing from Transverse Myelitis, although my Neuorlogist didn't rule out AIDP (which was his original diagnosis, although not officially). Also, the lumbar punture showed high white blood cell count. He gave me a choice to have 5 days of steriods and wait, just wait, or go get a second opinion. I am feeling somewhat better, but not completely. I still have twitching and some calf pain. Some days I'll also feel kind of nervous and weak, but it's not bad enough to keep me from working, etc. Then other days, I'll feel like great, almost like nothing is wrong, except a little calf discomfort. My questions is does this sound like MT, and should I get the steroids? I
