I have moderate bilateral l5/s1 facet joint arthrosis. is arthrosis the same as arthriti? and is this a condition that will fully heal?

See details: The terms in this instance both signify osteoarthritis. It will not heal although the back pain can resolve over time or with appropriate treatment.

Facet Arthropathy: Could be facet arthropathy/arthritis. There are joints in the spine where the bones articulate and can develop bone spurs and cause pain typically with extension. I would consider seeing a pain/spine specialist to see if facet injections or radiofrequency ablation would be helpful for you. While arthritis/arthropathy will not change, the pain can be reduced or eliminated.
