Pain in left armpit goes down to elbow,im female. It was here and there once in awhile type, now it has been hanging around two days or so, i notice when i lift or reach in movement its more noticeable. Thank you for your time. P.s Im not sure if its related,but...when i wake in am it hurts to move from pain in my lower sides of back, feels like things are mashed together and when moving im taring something,alone with occational shoulder blade kinda discomfort , i know that is not best description..sorry.
