DH and I were at the local grocery store Pharmacy earlier today and got the 65+ dose: Fluad Quadrivalent 05 ML INJ SEQI. Made the mistake of having the injection in the right arm instead of the usual left and unlike past years when there was no arm pain, my arm hurts a lot . DH has no pain whatsoever. As this is my first time with the high dose shot, I'm wondering if it's a reaction. Pain is similar to pneumonia shot.
