For most people, aches, pains and a mild temperature are the worst that might be expected, lasting a day or two. It must be vanishingly rare for something to develop that needs longer to recover from.
Well, you say that and then the very next poster had to rain on that parade.
Pfizer jab. Mrs D and I both had it on the 26th February.
Mrs D - slightly sore arm, otherwise no issues.
Me - next day my knees and elbows ached terribly, so bad that as I hobbled round the village walking the dog a total stranger stopped and asked of I was ok.
Day 2 I had a crushing headache.
Days 3, 4 and 5 I was fatigued beyond belief, and at its peak had to put real effort into even lifting my arms.
Days 6 and 7 the fatique passed, but it was still another day or so before I felt completely tip top and normal.
9 days in all before I was back to spec.
Interestingly, my Dad, who shares 50% of my genetic heritage, had a similar experience, although he perked up a day or so quicker than I did.
I take it as a sign that the witchcraft is now well into my system. I hope. Second dose is reported to give more intense side effects than the first, so Im clenching my buttocks with anticipation. Nevertheless, as unpleasant as it was it was hardly the end of the world - I could still move about and look after myself and stumble through daily life ok.
But whatever, I would still far rather go through that than have covid, thank you very much.
