Multiple Sclerosis
"I was diagnosed in June 22, 2012.  Started Tysabri August, 2012. I have never taken any other disease modifying medicines. I am JC negative. MRI in July 2013 shows no new lesions, no active lesions. I have never had a side effect from Tysabri. When I was diagnosed, my right leg shook so badly, I could barely walk.  I have drop foot, and weakened thigh and hip flexor muscles.  These symptoms have improved slightly.  I do not know if it is due to Tysabri or just how my MS is presenting.  
I chose Tysabri because I fall into the optimum category...no other meds and JC neg."
