Damn that does not sound good. That is exactly why I still question the shot.
As with everything in life there are tradeoffs.
If you do get the shot:
Most people have very reaction other than soreness at injection site and some have
1 day of "lethargic, pain in all joints, and massive headache". Klitlcker69 is the only case I've heard of that had it like that.
After that the vast majority are protected and even if you get the virus it is very mild.
If you don't get the shot:
you don't get the next day side effects — but if you get the virus some of the side effects can be (in order of severity):
death
damage to trachea from being ventilated that will effect you rest of your life
lethargic, headaches, foggy mind for for months not being able to work (I know of a healthy, trim 29 yr old that this happened to)
lethargic, pain in all joints, and massive headache for a week or so
blood clots (my 28 yr old kid had "covid toes" cause by blood clots from the virus.
and IMHO, the worst side effect is infecting others, and maybe killing someone you really care about
