If you go to the main page for all TOS threads - up above the main threads is a section called sticky threads - they have green circle icons with an arrow on it.

These threads have lots of important info & saved threads with links, polls, articles, pictures, videos, drs & PT lists, testing suggestions.

If you read thru those you'll find the testing info, and a poll of how all the old timers got injured and also a top 5 of symptoms as well as an all symptoms list.

Mine started as a RSI injury & then some shoulder injuries from repetitive work and then all came together to be TOS or TOS like.

some nurses here fell or tried to catch or lift pt and got TOS that way
also previous whiplash can play a part too
one got TOS from a vaccination
but most is due to repetitive/desk/computer/overhead work

most of us have ulnar and/or ring & pinky finger sx - usually all of us have had some sort of hand & arm symptoms along with the neck/shoulder sx.
