Husband and I both had Pfizer, and after the 1st dose we were both fine, just a slight tenderness for a couple of days. Although, I did get some redness and itching after 7 days, where the needle went in.
We had our 2nd dose on Saturday. We were fine on the day, but for a couple of days afterwards we both felt exhausted, and had lots of muscular aches, and hubby had a headache. Then, yesterday morning, I developed quite a large rash at the top of my arm, which is very red, itchy and slightly warm & swollen. It's also quite achey to lift my arm. After doing my own research, it seems to be a normal, possible side effect, so I'm not unduly worried. I hope it goes in a day or two!
