multiple sclerosis
"I was on tysabri for 7 months.... I think, at first I would be extremely agitated, tired and weak, by around month 4 I started getting pain in the top of my right hip have never experienced pain so unbelievably intense,  if it was even just slightly touched I would drop to the ground in utter agony, I began to slur my words and became emotionally unstable.  Tysabri seems to give me a much larger amount of MS which is annoying because they told me it had the least side effects and was by far the most effective. Glad to hear it helps other sufferers though . It's under PBS in Australia so they would only sting me for $37.50 a treatment."
