Hello & Welcome peaswink,
Somehow i missed seeing your post until now.
As finz mentioned, and from past posters history- it seems that the extra cervie rib surgery usually has the more favorable outcomes.
You do need to be sure you find the best surgeon you can.
They may suggest some PT first, just to see it it can help, before the surgery step.
Feel free to read thru some of the other posts or use the forum search link to find specific topics.
