I bought "Treat Your Own Neck" by Robin McKenzie based on the strong reviews at Amazon. I have a lot of neck issues (tightness, asymmetrical tension, pulling my jaw out of alignment, ...).
On page 4 under "Who can perform self-treatment?" it gives a list of people who cannot
and the first bullet is:
if you have pain near or at the wrist or hand and experience sensations of pins and needles or numbness in the fingers
That's not to say that you couldn't see a McKenzie-based PT in person and get a good treatment. But it looks like the book is counter-indicated for TOS.
