shoulders. Especialy before? my period. This pain is so severe that I can not walk, and can not lift my shoulders more than an inch, and i cant sleep. when i lay down i can hardly get up because i have no strength in my shoulders. once my period is over i usually return back to normal. However, I just started birth control again, and for the past week i've been taking it I have been in agony with the joint stiffness and pain. HELP!! what is this and how can i get it fixed? No pain meds work either!
