Left side and back pain ? This almost sounds like a cracked rib or ribs that's causing this and Ive had this and it hurt like heck but never for this long and also this rib may be touching a lung for some reason. Now i want you to test this and here's how to do this . take a 4 inch wide bandage and wrap or have someone wrap the body around all the ribs and make this tight for a while and lay down and see if this helps and if not then you should head to the doctor to see whats causing this pain.
