I had the booster on Friday evening. Saturday and Sunday I felt a bit nauseous but nothing major. Today I woke up feeling sick and had a sore throat. As the day has gone on I've felt more sick (I've not eaten for 12 hours and that was only toast) I've had one episode of loose bowels, I've got headache, I'm dripping sweat then I'm cold, my neck and eyes hurt.
Could this be from the jab? Negative LFT? Does it sounds like norovirus?
