2 days with upper right arm throbbing pain and shoulder, now feeling it going up to right neck area, pain increases when I try to lift my shoulder only in a certain way....throbbing pain is present even when I do not move it. Taking Aleve, which helps a little....I have to lay at night in a certain postion, I feel it more upper arm/shoulder joint area but also increases when I lay my head in a certain position. Do not really recall feeling an injury
