Botox is amazing for a large amount of chronic pain conditions caused by musculoskeletal abnormalities, as well as being used as a diagnostic tool for nervous system dysfunction.

I was pretty amazed reading a writeup about the facility in either Irvine or Anaheim CA that the toxin is processed at. They take the delivery/transport security incredibly fucking seriously because the amount is enough to kill a lot of people if used as a bioweapon iirc

The ability to turn specific nerves off and on again is borderline miraculous.

Hmm, I'm not sure about that - at least with Botox.

For what I was referring to - take Neurogenic Thoracic Outlet Syndrome for example. This is a very tricky medical condition, not yet fully understood in all cases, and requires ruling out a lot of other things.

For example, you're having symptoms of carpel tunnel or tennis elbow. Normally docs would do an EMG to see if the nerve has been damaged in the wrist or elbow. Nerves end up coming back fine - in the sense that there's no permanent damage, but the symptoms are still obviously there... now obviously, there's a larger tree of things to rule out/processes to do, but to keep it simple, we get to a point we suspect the issue is coming from the brachial plexus nerve bundle... we then inject Botox to the pec minor and scalenes. This eliminates the symptoms for some short amount of time, and thus indicates you would be a good surgical candidate to have your pec minor, anterior scalenes (or more), and first rib surgically removed, so that the nerve/arteries are no longer being impinged upon by the muscles/bone structure.

That is what I mean in the sense of using it as a "diagnostic tool"

However - Botox also helps with things like cervical/other dystonias. Sometimes, completely curing, but they really don't know exactly why in many cases. That is somewhat more of the turning nerves off w/Botox alone.
