@JugglingWithEggs@mstdn.social You can probably get some relief by 1. bending sideways away from the pain. (I.e. raise the shoulder on the affected side and drop the other shoulder), and then 2. gently twist the spine so that the non-affected shoulder is moving forwards and the affected on backwards. This creates more space between the ribs on the affected side so that the rib can set itself back in pplace.
