I woke up with severe neck and shoulder pain. i can't move my neck or right shoulder. the pain shoots down, could be spasms? should i get a voltaren injection and where can i get one today? or what should i do?

See a doc: You describe painful symptoms, but not a diagnosis as to it’s cause. See a PMR or pain doc for a work up to determine the why is this happening. Once you know the diagnosis, treatment options can be chosen. In the meantime, oral NSAIDS and other pain relievers make sense, as well as a pillow which provides proper support for both head and neck overnight. Good luck
