My left shoulder has always felt odd.... as if it is out of place. It doesn t exactly hurt.. but whenever I shift it up or down, I feel grinding and can hear/feel a clicking. My other shoulder does not do this and it is fine. Also, my left shoulder slumps 24/7. It feels weird to shift it up, more like a chore for some reason. Whenever I m wearing a hoodie or a jacket, the sleeve always goes down my shoulder to my elbow and it s really annoying. Also, it feels as if the circulation gets cut off or something.. I can t describe it. The big blue vein you can sometimes see in your hands feels like it actually hurts in my left arm . It makes my whole hand and wrist hurt from time to time. I ve had this all my life, from what I remember. I do game a lot, and I m always typing, but I use my right hand more so over use wouldn t make sense.
