My wife has fibromyalgia, but hasn t had a severe flare-up for weeks. She started feeling sore in the back of her neck, then it moved lower to her shoulder blade area, then her clavicles as well. As of right now, she has no fever or nausea, and can move her neck without any major issues other than it being extremely sore (almost like when she first started experiencing fibromyalgia symptoms). She also has a weak immune system, hypothyroidism, and hashimoto s thyroiditis. My concern and question is, given the point of origin for the pain and soreness, could this be something more sever aside from the fibromyalgia, i.e. meningitis or a staph infection?
