Hi @emiliaolga. I worked my way through lower back pain with doctors, radiologists, and physical therapists all focusing on bone degeneration, which wasn't the cause in the end. It was inflammation in one sacroiliac joint, where the spine connects to the pelvis.

This came a year after my wife's bone density tests led to a diagnosis of osteoporosis, later downgraded to osteopenia. Her experience raises the following questions for your doctor: Have your parathyroid hormones -- which control calcium balance between blood and bones -- been checked? How about vitamin C? Vitamin D? Is inflammation in your sacroiliac joints possibly the main problem? Can you perform daily low-impact exercise for an hour?

Best wishes for great care from your medical team and for gaining confidence in the improvement of your prospects.
