I got my pfizer this afternoon. I don't feel anything, no pain, no side effects, nothing. I even have a hard time checking where the needle was poked.
One mpa got her pfizer yesterday and she told me she felt nausea, headache, dizzy and muscle pain within a few minutes and then diarrhea later. She even warned me not to go alone. She still couldn't lift her arm yet. I guess everyone is different.
