Thought I would pass this on: It's a mystery!
I reported here that my sed rate jumped from 32 to 58 after my first Pfizer Covid vaccination. Interestingly, after the second jab it plummeted to 6- then rose to 11 a week later. I asked my GCA specialist what he makes out of this. His reply, "I don't know why it happened, but we aren't going to chase the numbers. We are going to go by how you feel."
Has anyone else experienced changes in their blood work post vaccination?
