tiny amount of discomfort at the injection site, that evening. It was completely gone the next day. No other side effects.

Second Pfizer shot: Yesterday morning…what a different experience.
Immediately after the shot, while I was doing my 15 minute wait …had a slight burning sensation where the needle went in. That lasted about 6 minutes or so and subsided. My shot was at 7 am, by noon I had a bangin’ headache that I could not get rid of. I thugged it out and continued with my day. That evening, wife and I were going to watch the Michael B. Jordan flick, but I was feeling type crummy and called it a night. Woke up about 4 am with more pain in my arm and a pronounced knot at the injection site. Also had a slight sore throat, headache, chillls and mild nausea. Took some multi symptom cold meds and watched some tv. Going to lay low today until this blows over.
