The test for TOS, well I have all kinds of test to determine that I have it. The main ones that prove you have it are a droppler test, and then an arteriogram test. It will prove that there is a blockage. I would recommend any repetitive work that you do, you need to stop, because it will make it worse. There is nothing else doctors can do for me, and I still have it. I was told there is nothing that will cure it, just help it. like a rib removal, which helped me about 30 percent, but then I got other symptoms, because they go under your arm, which when they cut, they also cut muscle and nerves, which can't be fixed. Really read up on this before you decide to do anything Best wishes for you. I hope you get better results than I did.
