I’m a 50 year old photographer and I had an mri as I suffer pain ( muscle spasm ) when I tween my back.

Here are some mri findings 
L4-L5: Small midline posterior disc herniation superimposed upon disc bulging deforming the thecal sac and mildly encroaching upon the right L4 neural foramen. Mild hypertrophic degenerative changes of the ligaments and facet joints.. No significant 
grade canal stenosis. No neural foraminal stenosis. 
 
L5-S1: Disc space narrowing and diffuse posterior disc bulging encroaching upon the canal and L5 neural foramina bilaterally. Slight retrolisthesis of L5 on S1. No significant grade canal or foraminal stenosis. Chronic discogenic degenerative endplate 
changes.
