Hi, Thanks for asking. Based on your query, my opinion is as follows. 1. It appears to be vertebral compression of lumbar vertebrae. X-ray would demonstrate reduced space between vertebrae. It is possibly lumbar spondylosis. 2. The radiating pain is due to compression of nerve in between vertebrae. Age related osteoporosis is possible cause. 3. Its not scoliosis. You need to get physiotherapy, back exercises and lumbar support devices. Hope it helps. Any further queries, happy to help again.
