I've been vaccinated and I haven't ever felt such a thing since, and neither do the other people I talk to who have been vaccinated. I haven't heard of such a thing from anyone or online before even. I'd guess you're in a depressed state, which can truly suck and which does feel physically wrong as well. Mental depression and anxiety can stress the mind and nervous system and immune system to the point where your body physically hurts or feels weird. I hope you can keep finding your way forward.
