hes , hi i have MS and i have had 4 strokes ( TIA S ) in the past 4.5 yrs , well its been a month and i have no function of my left hand and arm is numb , had a MRI with and without contrast and showed no stroke HOWEVER hospital wanted to keep me over night for IV Steroids but could not because i care for my parents who are very ill . Could it possible that i have had a MS flare up ? i have had them before but not this bad where i have no use of my L hand ! Also i had a chest xray done today and i have had a R node on my lung ,and today its still there but now my L lung has a bigger node what could this be ?
