My Dx; was the result of having an MRI and normal X-ray of the cervical spine which did show problems within my neck, but none that would confirm the symptoms that I was having. These done by the Neuro-surgeon that I was sent to by my work! However, in the past I did have problems with my neck, though never felt like what I ws going thru! The kicker was when I had PT done the second time the therapist did manual traction which caused both to explode with pain! That was the point that my faith in the Neuro-surgeon, PT and employee health Drs. was over and I sought help elsewhere and thankfully through investigation through the internet came about Dr. Togut.
Dr Togut did an amazing evaluation of my past history and a highly intense exam, and followed up with an EMG to confirm his findings, here again, he did not discount the cervical findings, but definately called Bi-lateral TOS and as I have been waiting for surgery have since decompensated and now am fortunate to be labled with RSD/CRPS!
When I went to Denver to see Dr. Sanders, he also had done a detailed past history, a major physical exam which included Scalene and Pectoral Minor Blocks that especially felt wonderful after flying out and only having an hour between the airport and the office visit. Though only lasted a short while which with all the rest of the info I had there was not doubt of Bi-lateral TOS!
This is how I was DX'ed and hope it is some use to others!
