My shoulder hurts really bad if I try to move my arm perpendicular from my body. I hurts so bad it has woken me up at 5 in the morning and has been hurting for about a week. This also happened about 8 months ago and hurt for about 2 weeks. It also “moved” (the pain) from my shoulders to my knees during that time.
