I had a nerve conduction test on my arm, it was pretty neat! I didn't find it uncomfortable, just a bit of a tingle.

My issue was a combination of a previous shoulder injury and bad sleeping position and bad sitting at desk position (resting forearm on the edge) that would result in numbness in my hand and fingers.

I'm more conscious of how I sit and sleep now (as much as you can be "conscious" of how you sleep!) and I started indoor rock climbing which has really transformed my upper body in terms of arm, shoulder and back strength and mobility. Funny, I don't look any different, but I can hold onto and hang off things well good. :P

I had one due to a bulging disc in my neck and some pins and needles - it was fascinating, but I still remember them turning on the audio and letting me listen to my nerves trying to flex various muscles! My biceps sounded like a bit like white noise (good), while my triceps sounded like a plastic bag flapping outside a car window (bad!) The way they explained it some subset of my tricep nerves were firing harder to try and compensate for the ones affected by the disc bulge - but they couldn’t keep up the firing rate by themselves. Really interesting and somewhat explained my mediocre push-up performance!

Similar story here. I used to have neck pain and shoulder frequently. About 2 years into bouldering, all of them are gone. And I have yet to face a jar I couldn't open
