Getting a sore arm following a flu shot is pretty common. I just got mine today and my arm is definitely sore. Mild body aches and a low-grade fever are not unheard of either. But, wow, your reaction does sound at the extremes of what is normal! You can develop allergies to eggs and stuff over time so you might want to get tested to see if you have emergent sensitivities.

I hope you don't give up the flu shots entirely (unless you are really allergic to eggs or thimerisol) because it is the shots are really quite effective against what can be a deadly viral infection. I was amazed at the number of normally healthy people in my town (who are also much younger than I am) who got seriously ill with the flu last year and required hospitalization.
