I am new to TOS also. I do not have an official diagnosis. My chiropractor is referring me to a neurologist for "nerve testing" The worker's comp, Independent Medical Exam (to see if I am faking) Dr., confirms that I have nerve involvement and that I should be seen by said neurologist to investigate the brachial plexus.

I have learned that Drs do not like a patient to tell them the suspected diagnosis. It seems like they will find every other cause but what you suspect. So, only give your history , and of course, every symptom that makes you suspect you have TOS and your suspected causes.

It sounds like the neurologist already suspected Thoracic Outlet as the cause of your suffering. She sent you to physical therapy for it. I would try to get a follow-up appointment with the same neurologist.
