I’ve had excruciating pain between my shoulder blades since before Christmas……..
This is a serious thread and question btw. :)
Have you checked yourself in a mirror recently for any sign of an object sticking out of your back??? This pain could be caused by somebody having stabbed you with a bloody great big carving knife, or similar.
If you see a handle shaped object sticking out, this might provide a slight clue.
