Excuse the unimaginative username 
I got the jab on Tuesday and holy cow my arm is killing me!! Hot, swollen and red and not even at the jab site which I thought was strange.
I'm not overly concerned as I vaguely remember this one being a bit sore the last time but jeez it's like calm down already! So painful! It's actually been making me feel quite unwell.
A couple of paracetamol and a cold compress has helped the past couple of days but have woken up with it back to being as sore as ever
