Facet joint disease

I have bad facets in my entire neck. When I was 40 I tried nerve ablations at C34, C45, C56. Nerves grew back and had to get fusion.
My cervical vertigo was from C23, just had an ablation. Next is ablation C67 to get rid of body cramps and entire tight body, at 65 hopefully it won't grow back

Is facet joint disease same as arthritis? And what is the difference between cervical arthritis and osteoarthritis? My rheumatologist said arthritis is diagnosed via hands and feet thus i do not have it but other doctors mentioned facet joint disease and arthritis on the neck.. And how is regular arthritis and rheumatoid arthritis diagnosed differently? My acupuncturist said rheumatoid arthritis but western says no.

arthritis is simply inflammation in the joint.
Cervical arthritis is inflammation in the joints at the side of any or all cervical or neck vertebra.
Osteoathritis is when the cartilage in a joint becomes damaged with resulting bone changes--disintegration or bone spurs.
Rheumatoid arthritis is swelling that results from autoimmune disease where a person's body attacks the cartilage in joints. Without treatment RA results in the disintegration of cartilage and then bone in the joints. RA is suspected with bilateral pain in hands and/or feet. Diagnostic testing includes serum blood draws for rheumatoid factor and xrays of the hands and/or feet. Disintegration from RA can be halted by methotrexate and monoclonal antibodies like Humira.
I have cervical osteoarthritis. In my neck bone changes at C5-6-- osteophytes (sharp little bone spurs).
I get tested for RA because there is a strong genetic component and my sister, an uncle and a cousin have RA. My sister was treated early and has no damage to her joints.
