I've been suffering severe pain on the lower right side of my back, so I've just had a ct scan of my lumbar spine. It found severe bilateral foraminal stenosis at L5/S1 as a result of degenerative disc osteophyte complex herniation. There was also focal Central to right paracentral disc protrusion on the right at L4/5, measuring 10 x 6mm, effacing the right lateral recess, potentially impinging on the nerve. Apart from the disc impinging on the nerve I don't know what any of this means. Can you please explain it in layman's terms & likely treatments for it?
