My back always get put out and i see an osteopath to get it fixed however it always happens, i can only assume its due to knots in my shoulder blades, possibly from working behind a computer each day, however more recently i have been getting the only what i can explain as knots in my chest, same place i think that they are on my back but in my chest and sometimes when i move sudden or move direction i get a sharp pain. Can you tell me if this is something to worry about
