Half the battle is done, at least you know about the extra c ribs and that they are a major factor for your TOS.

I think the skills & knowledge of the top TOS drs is much better now than 8 yrs ago. There are also many more qualified surgeons than there were back then.

Recovery isn't easy but there have been many more good results being reported this last year.
Having a good support system at home is very helpful.

Many have traveled for surgery and with lots of extra pillows/padding and a careful driver, they made it home fine. The dr won't release you until they feel all will go well.
