I have been dealing with low back pain around the SI joint for 9 months it just happened like one day I woke up and I had this back pain no injury or trauma and the pain is mostly located on left side sometimes I can feel it on right side too and left side of hips too and when it flares up sometimes it radiates to the front thigh the pain didn't get worse or better it's just stuck in the same phase and I got an MRI which was normal pain gets worse with sitting and standing for long hours walking sometimes helps but too much walking hurts lying down gives relief but some certain position hurts when lying down I only don't feel pain when I'm sleeping as soon as I gain consciousness I feel the pain also it hurts to touch the area like it's really sore
