The conditions of Enthesitis/Enthesopathy are almost never heard of these days. Where did they go?

If one compares the symptoms and the manifestations, they seem identical to Fibro. Enthesitis is the inflammation of tendons and ligaments, -opathy is the degeneration of the same.

I don't know why these known conditions get caught in these diagnostic whirlpools and disappear to re-emerge downstream as fibro.

It makes sense that females would suffer from ligamentous conditions as females are subject to the hormone Relaxin that allows for the fetus to grow and for females to give birth. Joint laxity in females allows for that process and it is not inconceivable that somewhere along the line, it becomes problematic.

Many people with Fibro are not offered epidermal nerve fiber density testing, and could conceivably have SFN, others could have the multitude of conditions that all of us know can take years and years of dedicated diagnostics to find, and until then, Fibro is what their malady is named.
