It is three weeks today since I had my first infusion. But, now for the past 4-5 days, I have had very red irritated, watering eyes, burning/tingling/aching down my right arm, burning mouth, extreme fatigue, vibrating sensation in my left buttocks and down my thigh, as well as a severe migraine for 4 days straight, and this feeling of an internal tremor (I have never had this before) it is from my brainstem area to my stomach....like I am shaking inside.

Do you think this is a Flare? or a reaction to the Tysabri? about one week after the infusion, I had a irritated, runny, congested nose...and off and on abdominal cramps (that lasted about a 5-6 days)
