The CDC site does confirm that reactions like mine, while not very common, do occur:

"The flu shot: The viruses in the flu shot are killed (inactivated), so you cannot get the flu from a flu shot. Some minor side effects that could occur are

* Soreness, redness, or swelling where the shot was given
* Fever (low grade)
* Aches

If these problems occur, they begin soon after the shot and usually last 1 to 2 days." -- from http://www.cdc.gov/flu/protect/keyfacts.htm

I'm not going to bother getting tested for an egg allergy. Been eating 'em for years with no problems. Fortunately I feel a lot better now.
