Got the flu shot yesterday. I've gotten a flu shot every year for as far back as I can remember, and yesterday is the first time that I've had a really bad reaction. It gave me the works: severe back pain, nausea, vomiting, and weakness. I'm taking comfort in knowing that I have some protection and that my reaction is not uncommon. Feeling much better today, and no longer fantasizing my hands on the throat of the pharmacist.
