Were you allright before injection?
Yes, I was fine.
Where injection was given?
The booster was given in my arm and I am do not think I have a fever nor do I have a headache but a very, very stiff neck and upper back.
I have felt a little nauseous all morning.
How many hours before injection was given?
Three hours or so.
Pain and numbness at injection site, headache , nausea , dizziness can occur as side effect of medication.
Stiffness in neck and upper back are not usual side effects of vaccination.
At this stage you should wait and watch.
If there is progression of symptoms you might need medication and proper medical attention.
Meanwhile if there is pain and fever you can take tab ibuprofen.
