I have Mixed Connective Tissue Disease (genetic, diagnosed with blood work) and fibromyalgia is part of the overlap. Movement is so important to move the fluids that press against muscles and tendons, presenting referred pain. A daily walk and general stretching make a huge difference. Rest just lets you rust. Keep up with non-processed, low sugar foods, too as sensitivities lead to pain. I got images of sore joints, and no bone issues; it is all soft tissue woes. I avoid supplements for the most part, but magnesium citrate and D3 help.
