Tremors, difficulty with speech and walking, head shakes! Auto immune disease?

@Zoffiel and @Irb_03 I can't make too hasty a decision because it may not turn out to b any of the chemo drugs, rather my body's auto immune response to having the cancer or the chemo drugs.  My neurologist said yesterday that even tho those 2 drugs r contraindicated he doesn't believe it is serotonin toxicity.  He is still waiting on lumbar puncture and blood results to test for myasenthia gravis (I have lots of the symptoms) or fungal infection. 
Anyway it will b interesting to hear the 2nd Opinion Oncologist's thoughts today!
