I have been dealing with unexplained muscle aches & soreness for everyday years. On days leading up to & following my period, it's the most intense & uncomfortable that I struggle to get myself up and sometimes cannot. It feels like intense aching, tenderness, and soreness. I feel it in every muscle in my body from my cheeks aching, my fingertips, my arms, my torso, my back. etc. It is not my joints aching, rather my muscles and it is NOT relieved at all by OTC pain meds. What's going on?
