I have moderate facet arthropathy at L4 and L5 what can help to treat it or fix it. What is it. Does it cause pain to walk.

Avoid extension ... Facet arthropathy is arthritis in the posterior joints of the spine. Any arching of the back will aggravate your condition. Axial loading is also not recommend. You need to keep your lumbar spine flexed and avoid any arching of the back. Hip capsule & flexor stretches will help maintain your posture. You need to see an physical therapist after the orthopedist writes the appropriate prescription.
