question: Hi, I have back pain for almost a year (bulging disk), which got better with exercises. Now I have a painful spot on the lower spine, which I did not feel before, a little sore at touching but feels like a bruise when pressed. It is between the vertebrae. It also hurts when straightening my back while standing. Is this also from the bulging disk? Or maybe ligaments or muscle (I have stopped physical exercises suddenly, I guess I should have done it progressively). Thank you!
