Well if the symptom differentiation was straightforward, I suspect Drs would take a stand. In reality i suspect most of us with TOS present with a bewildering mixture of postural issues, muscle imbalances, trauma to the shoulder, cervical areas, that only the most comprehensive Dr or medical system will patiently examine each and everyone and exclude. Most will just do some stuff and then give up and use CRPS, Fibro and TOS. Plus folks dont talk to one another. A rheumatalogist recently noted many Fibro patients are in reality those with undiagnosed neck trauma.

Worst is all three conditions coexist or are suspected to.. very hard to differentiate what is what in that case.

I wonder which Hospitals or Drs do this sort of comprehensive workup.. might be worth marking them out.. above and beyond the TOS list.
