Fibro flare-up caused by flu shot?

I got a flu shot the day after Labor Day (I protested, but the doctor said it was not too early) and within 48 hours after that I felt like I had been hit by a Mack truck! Every inch of my body hurt (except for my hair) and I constantly felt like I was "coming down with something". Who else has experience this? I am scheduled for a shingles shot this month and I really don't want to go through this crap again. I have had fibromyalgia for over 20 years and have never felt this bad for so long before this. Just within the past day I have started to feel human again, but probably because I started taking a probiotic from GNC. My family physicians (I have had two in the past 5 years) will acknowledge that I have fibromyalgia but just want to push pills at me. Don't want to take any medication. Need to figure out how to treat this naturally. HELP!
