I am struggling with some biomechanical issues in my upper body that are intersecting poorly with the inflammation of my ankylosing spondylitis and psoriatic arthritis.
The upper fibers of my trapezius muscles are killing me. I presume I have some soreness and pain as I’ve been incorporating a new slow progressive full body workout program. But a little digging is making me reassess that conclusion.

I’ve been patiently working the problem of my inflammatory issues for literally half a decade and yet I am regularly finding new information thanks to the wonders of deep research products.
Somehow I had never really researched enthesitis despite it being a fairly core symptom in my case presentation of spondyloarthropathies.
It is an inflammation where tendons and ligaments attach to the bone and I have it something fierce in my intercostals and trapezius muscles.
There are many other areas where enthesitis can occur, he says, including the area where the ribs meet the breastbone, the back of the head where it meets the neck, and in the spine in the area closest to the skin. Creaky Joints
It’s possible current pain not delayed onset muscle soreness at all. It’s enthesitis. I don’t know if my new IL-17 inhibitor is working as it should but the strain of my new workout regimen is just a part of a wider issue in my condition. I’ve got a deep dive running on exercises but right now I’m going to take a muscle relaxer (magnesium) and lay down.
