Covid vaccination side effects?

I am a 31 year old female, I just got my booster dose of the Pfizer covid vaccine. About 15 hours later I have warmth, pain, and swelling at the injection site. I also have armpit pain. Is this normal? I am afraid the warmth means infection.

Thanks for the question.
These symptoms indicate that you are responding to the vaccine. They should subside within a week or so. If not, that would be the time to see your doctor, or earlier if it worsens instead of improving.

Your symptoms are seen after vaccination. Obviously can also be seen with early infection, but more likely just your immune response. Monitor your temperature and evolution of symptoms. If due to vaccine induced symptoms, they will level off, if worsening, then see a doctor.

Perfectly normal response to many vaccines including the Covid vaccines - nothing unusual.
