since mid December 2014, have began to develop pain in right shoulder and arm, the pain seems to move around. have felt it in my upper arm, elbow joint area, forearm, and palm of my hand. I do a repetitive motions job where my right arm and shoulder is used extensively, and this does make it feel worse, but feels better with Aleve pain relievers, and rest. but it still lingers even during my days off. has not completely gone away. on my off days, I feel these sensations intermittently, one minute I feel like its not there, and then i'll get a mild but noticeable surge mostly in the top right shoulder area, and sometimes in the upper arm and lower arm area. it just seems to hang around even when at rest. am currently doing shoulder strengthening exercises at the advice of physical therapist. this pain does not seem to associated with any noticeable loss of range of motion, or strength needed to do my job, but it does feel exhausted somewhat after a strenuous workshift.
