IVIG starter dose POTS

Holy guacamole! IVIG starter dose update: So the second round of IVIG Starter dose had a delayed response to side effects. I had the worst migraine of my life along with POTS and the flu like symptoms. My home health nurse is amazing and came to my aid to try to counter react it. And neuro did step in. We did not do the last dose of the starter dose. I am waiting to hear back from doctors but nurse thinks we should be able  to continue since I did well the first day and that's the dose from here on out. Also they should have pre treated me for migraines since I suffer from chronic migraines and it's the most common side effects. It was rough. Today is better but still not well. One day at a time- Chelle
