Hi Stellajane.
I had the flu jab a few weeks ago, and although my arm was sore for a couple days after, I didn't get any redness or itching where it actually went in...
However, I did get it when I had the pneumonia jab a few years back. Think it lasted a few days, then settled...
I think some people do get a reaction like you have, others don't, hopefully it'll settle down
for you in a couple days...x
