Julie Freischlag, Surgeon-in-Chief at Johns Hopkins with a specialty in TOS, posted a video on TOS at:

She pointed out that many neurological tests show up negative because the nerve is compressed, not damaged. She then pointed out various other tests that are useful for diagnosing TOS.

She mentioned that botox injections could only be done once or twice because then the muscle doesn't relax any more. I hadn't heard that before.

If you're new to TOS, this may be informative. Otherwise, you already know the drill.
