I’ve had lower back ache now for about 2 months. Initially thought I’d pulled a muscle at the gym. I went to the doctors and they said they thought pulled muscle and to see how it goes. The pain is a dull ache and hurts more if I move or lean in a certain position. It went okay for a couple of days and then last week I woke in agony again, as if I’d slept funny. I’ve had a spine X-ray which picked up a mild scoliosis but gp said that shouldn’t cause pain. I’m starting to worry now. Any idea what it could be or could it just be a pulled muscle, the pain does coincide when I was doing some new weights in the gym and did start a day or so after
