I was given 1000mg IV infusion of methylprednisolone sodium succinate for my MS. I am coming off 60 months of Tysabri infusions because of 2 allergic reactions. My doctor wants me to go to Copaxene now, but I am 58 with secondary progressive ms. Now, after 4 hours, I am having major issues walking, lips are numbered, major headache, tingling sensation throughout my body, high heart rate, shortness of breath, and blood pressure going up. Should I be concerned?
