I am wondering if this is a simple muscle strain or something more. 10 days ago I worked out to my usual routine, but I also was sliding and moving some really heavy boxes at work that I shouldn't have been moving. The next day I woke up with this pain in my right upper back/shoulder area. The strange thing is that it only hurts when I flex my head forward and back and to the left. It feels like a sharp pain that is running down my upper back to the right of my spine and into the shoulder blades and does not hurt when resting. It's been 10 days and the pain is still there. It's not horrible and I don't have to take medications or anything but I am getting worried.
Could a simple muscle strain cause pain after all this time? I haven't exercised it or gone to any PT or anything. Also, what muscle is it that I could have injured?
