You can ask, as long as you don't expect an answer! I don't really know!

To be more precise, I certainly did--and still do--have entrapment PN, in various places all over my body. (It comes and goes, at much milder levels.)

My hand pain, for instance, seems to have come from entrapments in my neck and thoracic outlet and underarm and on my arm--all at once. It's a double-crush syndrome, whereby one pinch makes the nerve more vulnerable to other pressures all along its length. My cervical vertibrae were so tight I could literally hear them move; my PT used a "wedge" and traction to open them up.

I still have bilateral elbow neuropathy. I wake up with tingling numbness in my ulnar area, sometimes just the hand, sometimes the whole elbow side of my forearm. It goes away with movement or straightening my arm.

All that said, I don't really know what happened, or what caused what. My onset was extremely abrupt and followed viral illnesses and inoculations, so autoimmune reactions have not been ruled out at all. Did my connective tissue have the reaction, or did my nerves develop PN and become more susceptible to irritation? No one knows.

Also, it's important to remember that myofascial pain is itself a neuromuscular condition. Trigger points are considered to be dysfunctional endplates of motor neurons, and what causes that to happen, nobody knows.

Confusing enough for you?

ETA: Aussie, I've always felt, reading your posts, that you have exactly the same thing I had. While the causes remain a mystery, I do know that the treatments worked!
