Hi Lisa--I am sorry for what you've been through. Yes, we seem to have different problems. But we both have the identical dilemma. Which vaccine did you get? I may get the J&J (even though it seems pointless since it is not as robust as the other mRNA ones) or Novavax when it becomes available. Novavax was suggested to me by a neurologist I wrote to. That's because it and J&J work differently from Pfizer and Moderna. On the good side, there seem to be medications to now help treat COVID if we do get it. We may not die. Honestly, I wish we had a neurologist on this site who could give definitive, medical advice. Volunteers, have you ever thought of getting some MAYO doctors to weigh in for us?
