I also am joining you all with the exact same experience, that also was in 2010.  The night I had the flu shot (which I take every year with no problems) I developed severe chills and a light fever, dizziness, and nausea.  The next day a reddish bump appeared on my forehead , which spread to areas on my face.  I went to the doctor, who diagnosed me with shingles. I asked if the flu shot had any connection, and was told no, it's just coincidental.  After hearing all of your similar stories, I see that is not so.  The question now is if we should continue taking flu shots, or not?  Maybe it was just that year's strain, or are we now more vulnerable to future shots because of our reactions?
