I am only 46 but have had back pain, not just lower, and joint pain since I was 19. Yes, you can have it from just bending down, turning, twisting or sometimes from just sleeping. When I have something acute like that happen I see a chiropractor. This and excercise helps me a lot. Sometimes my back pain is so acute I can not get out of bed. Sorry to hear you have to deal with this and I hope it will be over soon.
