i did not get one last year and had the flu so bad that i decided to pursue the flu shot for this year. when i called my primary care office, the nurse on duty told me that fibromyalgia is not a criteria for being accepted for the flu shot. i was so taken aback by that! i mean she was wonderfully nice but i told her how backwards that sounds!!! once i told her that i work in the health care field per diem she immediately signed me up....i had it all in one dose and had no side effects. find a way to get one---even if you need to bring a fold up chair for those of you who have difficulties standing in long lines!!! do what it takes.
