Hi, i want to ask you what probably the cause of my lower back pain. I have problem with it since mid last year, it's not that bad, sometimes it feels okay but sometimes it's really painful that i have a problem where i have to bend ( tie my shoes, etc). I have already do the urine test, the result turns out good. I also have already get the x-ray scan, and it also good. Well, i have a slightest pain in my lower left stomach, and i'm a woman. Do this have any relation with it? What could be the cause of it? Or could be this be a somatization?
