Hi pinkynose!

To me it seems reasonable with the connection between the flu shot and your SFN flare.
I seem to be getting an increase in pain/tingling/numbness everytime I get a cold/fever. I've got a similar behaviour with an increase on the onset of the cold which peaks and then subsides over a couple of days after the cold/fever is gone. The connection for me is quite clear and I do my best to boost my immunsystem as to avoid this.

Is there anyone else who has noticed a similar connection?
