For a newbie, this is so overhwelming.....

These are probably side effects and will more than likely pass as your body gets accustomed to Tysabri (as a few others have reported this too, and they said that it passes in a couple of days as well - and it doesn't happen with each infusion)...your worry is more than likely adding to your sleeplessness (I'm just guessing as I'm not a dr.) Try not to worry as it causes stress and stress + MS don't mix well, as we all know.Pain, sleeplessness, and of course worry
