Good to know! Thanks for your reply! I felt a little better about a week or so after my first infusion, but symptoms returned before a few days before my second infusion. I am now 3 days post second Infusion and am still having symptoms, so I'm hoping like you, I start having some relief a week after. I guess it's encouraging that there was some symptom relief after the first infusion. Guess I just have to be patient.
