I was diagnosed with Fibromyalgia in my early 30's as well (48 now). High humidity causes pain, tiredness and brain fog. I have also been in 6 car accidents and have 2 herniated lumbar discs, bone spurs in my hip, sacrum and lower back, osteoarthritis throughout my spine, and had a shoulder scoped and shredded bicep tendon cut away on the same side. I've been going to a physical therapist that treats fibromyalgia 2x/wk for almost 2 months now. with a focus on neck and upper trapezius tightness. But I'm hearing a lot more about how Fibromyalgia and endometriosis have similar symptoms- however my PCP won't discuss further because the one who diagnosed it "must have had good reason" and because that diagnosis requires surgery (one I already had back then, which showed that I had part of my colon fused to my uterus and resulted in a hysterectomy a few yrs later). I don't want to be taking drugs for fibromyalgia just because another diagnosis is too difficult.
