hello my name is CHERRY KELLEY, I have ms, my question is, I was on TYSABRI & I received the T~virus so now I am now taking sterioids, but, I have a headache in the back right side of my head, I think it can be a result from a bad cough& cold. I did go to the hospital for treatment , received meds on 9~22 but I know the meds didnt wok, still have the bad, bad cough should I go to the EMERGENCY room
