As you obviously now know...one does not need to have a fracture to have continuous back pain. There are all sorts of possiblities when it comes to back pain. Could be something as minor as a pulled or strained muscle...or...a more serious condition such as a disc herniation/bulge, vertebral slippage, stenosis, degenerative disc disease, etc. See a spine doctor and have an MRI done to determine the cause of your pain.
