flu shot and hives

My son and I recieved a flu shot a week ago.  He developed hives on the arm immediately that lasted for one day.  I had no symptoms immediately.  Six days later I developed extreme hives and still have them several days later.  I have never had an allergy except the minimal seasonal hayfever allegies.  I have had no change in detergents or foods or any of the other simple suspects.  I am otherwise in good health with no other symptoms.  I am taking medications (Pepcid AC and Benedryl) and the doctor also prescribed steroids.  I have never had hives or any extreme allergic reaction to anything before.  Could this be caused by the flu shot and how long will it take to disappear?  Some doctors say no way was this caused by the shot but one I talked to recommends that I do not get the H1N1 shot becuase he feels that it is possible that it was from the shot.  I am definitely not allegic to eggs either.  This happen to anyone else?

Hi,
How are you? Hives are red, itchy, raised areas of skin that may be caused by a variety of conditions like stress, food, medication, and even allergic conditions itself.  Hives are produced by histamine and other compounds released from special cells.  They usually resolve on their own over a period of weeks, and are rarely medically serious. H1N1 shots cause mild but common reactions like sore arm, redness, swelling, headache or fever. Take care and best regards.

I too have had extreme hives - for 5 weeks now, after having the flu shot.  My hives only started 2 weeks after the flu shot, but I am convinced they are caused by it.  I too have never been allergic to anything, and have not changed anything in my diet or environment.  This is in response to the 2011 flu shot - has this happened to anyone else?
