Painful legs afte 2nd jab

Vaccination technique counts too of course. My first one I felt the needle go in and it seemed to take ages. That was by an army medic. The second one was administered by a nurse and I quite literally didn't know he'd done it. Obviously really good at injecting. Similarly my flu jab last year was absolutely painless.
Perhaps lemongrove the vaccinator struck a nerve or ligament?

I could hardly move my arm after the Pfizer first jab, it remained painful until almost the time for the 2nd one.Ever since then I can’t move my arm properly, and it feels ‘weak’ and also painful if I lift it up.I think this vaccine takes everybody differently and in different ways.I suppose it will just take time.

No problem whatsoever for me DH, DS and friends that had the Pfizer vaccination.
There are many possible causes for leg cramps. They could be just coincidental?

Do you know about the yellow card eporting scheme? Also magnesium either oil skin spray or taken orally can help with leg camps

Nothing with me, nor anyone we know.
