im 17. i started my gardasil shots back in October. a week or so after the shot i began to get frequent headaches that were more severe than any headache i have ever had. like others i also began to itch all over my arms and i developed a vaginal itch that my mother and i thought was a yeast infection. we treated it like a yeast infection and it went away. i then went for my second injection last month. after receiving the second injection the itch came back more severely. i am glad i found this site and that i am not the only one being hit with out of the norm side effects that the doctors give us. i also found another site that says that the gardasil shot can cause P.I.D.
