do your arms feel heavy and tired when you raise them up?

do your hands turn white if they are up for very long?

here's a link with pics of "positional testing " most good care providers should do at least some of these to help rule in or out TOS.
not a definite but a reason to do more testing.

[EAST Test or "Hands-up" Test
The patient brings their arms up as shown with elbows slightly behind the head. The patient then opens and closes their hands slowly for 3 minutes. A positive test is indicated by pain, heaviness or profound arm weakness or numbness and tingling of the hand. ]
