Soxx, I agree w/ Finz.

TOS stands for Thoracic Outlet syndrome, there is a section here on Neuro talk about it.

I suggest you see a good neurologist (one that's familiar with these disorders), you might need to see a hand or thoracic surgeon (for a dx) also.
I too have these disorders, (amongst others) they're managed, not cured.
I'm not dx ing you, but you should have these things ruled out! (or in).

If you're near a fairly big city, I suggest you find the 'Cheif of neurology' at a teaching hospital (university). It took 7 years for me to get a diagnoses, and it was from Dr Schwartzman in Philly.
(I understand he's now retired).

I hope this helps, and please understand, I'm not trying to diagnose you, just tell you a little of what I've been through....

Hope you get some relief!
