Pfizer Covid booster

I just got my booster and flu shot yesterday. Last night I had a headache. Today I have body aches plus I’m a little nauseous. I’m pretty sure it is from the Covid shot. I felt this way with the original Covid shots (not boosters). Just wondering if anyone else here had issues with this booster.

It's likely a good sign meaning your immune system is working.

However, it it lasts more than 36 hours or so, I would get checked out, in case your reaction is due to something else.

I've had 10 or 11 Covid shots, and my reaction to this latest booster was the same as all of the previous ones.

My wife had "flu shot achies"

I was fine.

It was suggested we get the flu shot 2 weeks after

After getting Moderna in the past. I was totally wiped out. Got flu shot at the same time too. Never had that happen before.

I had a sore arm and, so far, that's it. I ordinarily get a 103 fever, and a month of migraines. Hoping the minimal initial reaction means I will also escape the month of headaches.
