@janeram, you are going through a lot. Am I understanding correctly that you have kidney disease, COPD and lung cancer? Those are conditions you've been managing for a while. However, you most pressing concern right now is this scary allergic reaction that may be from the mRNA vaccine. Is that correct?

Have you or will you be seeing an allergy and/or immunology specialist?
