I have fibro and have now had both doses of Pfizer.
After first one I had a mildly sore arm for around 12 hrs.
I’m currently in bed having had second dose on Thursday, was fine til Friday late afternoon when started to feel grim and have been in bed since feeling like I’m recovering from a bout of flu, heavy achy limbs, joint and bone pain, swollen and painful glands in neck and under arm.
On balance however, I’d rather this and the likelihood of side effects only lasting the predicted 48 or so hrs than getting covid, and I don’t think my fibro has had anything to do with causing the side effects as were all mentioned as possible ones to expect, and second dose is more likely to cause a stronger reaction.
Anecdotally, I’ve heard of far more people suffering worse side effects with AZ than Pfizer, and having volunteered in a number of vaccine clinics over past few weeks, I’ve seen 1000+ people vaccinated with Pfizer, and yet to see anyone have a bad reaction
