Hello, this feels ridiculous but last sunday the 11th I sneezed and felt something in my thoracic spine/ribs go , it is still feeling quite odd, like it needs to be clicked back into place but none of my movements (side rotation, flex/ext, side flex) have been painful. The strange feeling has not subsided and I now have a slight chest pain. Just wondering what I might have done? Have I possibly just pulled a muscle? Thanks!
