I have wondered the same thing as I had TOS due to a car accident in1988..Two years after the accident I had to have both of my first ribs bilaertially removed..due to impigenment AND during both sugeries my thoraxic Dr. cut my sympathetic neve in my chest. He felt it was in protocol of the surgery..Now 20+ yrs. after I have RSD...I have asked countless times, even Dr. S in Pa. if that could have contributed to my RSD he said possibly..
Interesting!!!!
