Look i have had RSD 31 years i was also told i had TOS they did the 1st Rib removed, I did not have TOS the doctor at mayo told me i should of never had that surgery to remove the Ribs but TOS and RSD have same systoms but are not the same also with RSD you will get changes in the bones that's what i'm going through right know i need to have shoulder replacements , the Doctors also told me if we cut the nervs for rsd and they miss one you will have a bigger problems also you will never be able to get nerv blocks because they will not work JUST MAKE SHURE YOU KNOW WHAT YOU ARE DOING AND KNOW ALL THE WHATS IF YOU GO A HEAD WITH THE NERV CUT SURGERY. what i know know i would not went with the TOS surgery and they will never cut my nerv on less they can give me 100 % shure my pain will stop this just my opinion
