@redboat I'm not suggesting you have reactive arthritis. You have to go with whatever a doctor tells you and I'm not a doctor.

Reactive arthritis is just one type of spondylitis. There are 6 types but that was how they were classified in the past. There has been a new classification system that recognizes just two broad categories.

Peripheral spondyloarthritis (pSpA) typically causes inflammation in the joints and tendons outside the spine and sacroiliac joints.

and

Axial spondyloarthritis (AxSpA) causes inflammation and pain in the pelvis, the spine, or both.

You can also have a combination of both peripheral and axial.

To make it even more confusing ... you can still have PMR in addition to spondylitis.

In my case, PMR was diagnosed about 20 years after reactive arthritis and uveitis. PMR just blended into what was already an inflammatory mess. My rheumatologist mostly referred to widespead "systemic inflammation." and not necessarily any specific diagnosis.

In my opinion, it is the inflammation and pain. that needs to be stopped. I used to tell my rheumatologist that she could call "it" whatever she wanted to. I was at the point where I was willing to try anything.

The biologic I am currently taking was a nice surprise. I like my biologic much better than prednisone. My biologic was targeting the inflammation cause by PMR but it isn't FDA approved for PMR. My rheumatologist just had a hunch that it might work in my case.

There are many biologics that target different things. It is more about finding something that works better than long term prednisone. There is no cure for most autoimmune conditions.
