I have been diagnosed with M.S. and also tested positive for the JC Virus. I get a 3 day I.V. steroid treatment, and usually I feel better. This last time,(Friday was my last day) I have felt crappy. Very swollen, rash on chest and across my cheeks, confusion /dizziness and terrible dry throat little cough, and headache and back of neck pain. I told my neurologist but they seem to think it is from the treatment. I am on depacote, steroids, tecfidera, vit d, asprin, and a benedryl at night. My cousin has M.S. and was then diagnosed with Lupus. Is that a good posibility?
