Signs of Arthritis: What you relate are signs of arthritis radiographically speaking. I'd've expected this type of picture more from an older person or one who suffered a significant injury to that area of the back or has been doing extensive repetitive bending & similar work for YEARS. If you were to modify what you do with your back you could slow this down. If not, then, unfortunately, YES, it could progress.

Report: quite technical but not dangerous. I suggest that you DO NOT MIX ibuprofen and Naprosyn (naproxen). There is no sign of damage on the report as you noted it.

How old are u?: These are NORMAL degenerative (wear and tear) changes for a working adult age around 50! Slow worsening will occur (Emphasis in SLOW) Not to worry! Hope this helps Dr Z

Spine MRI?: facets are the "joints" between the vertebra in the spine. Facet changes refer to degenerative bone process that can be a normal part of the aging process. After a certain age we all have them, me included.
