Recently received a blow directly to spine between shoulder blades didn t feel any harm until next day, it felt like my Shoulder was dislocated, painful, it has elevated and travel down arm to nforearm and is much like a burning or carpul tunnel pain although throughout the entire regian of back shoulder and r/arm where the pain stops is near wrist and it is especially sensitive. Does this sound to you like nerve damage, could it be perminant, especially the pain?
