I also had been experiencing backaches and fatigue, and I noticed that my arms and hands had swollen a little bit--not like an allergic reaction, but like an intolerance to something I ate--so that my watch and ring were snug instead of loose. This bothered me because I've been working so hard to reduce my arm/ankle/stomach swelling, and I'd made lots of progress. So why the backslide?
 I
 had a memory surface in my brain about how my husband reacted when he 
took cholesterol statin medications.  Each time he'd get the same 
overall body aches.  So I had to trace back what we had both been eating
 for a week and a half.   Bingo!!!   The turkey.  I've been feeding him 
turkey sandwiches and making soups from the leftovers from Thanksgiving 
Dinner 10 days ago.  I'm certain that it wasn't turkey itself, but that 
it was the chemicals and hormones the turkey was fed that made it 
intolerable to our systems.

Perhaps when you feel swollen, bloated, achy or pained, you could trace back what you felt to what you ate. The swelling in my hands, wrists, arms and stomach went down as soon as I stopped eating the turkey in any form. Diet makes a huge difference. Is there something you are intolerant to as well?
