You probably did a search to compare BN vs TOS already.
but I'll add the results link for future readers too -

One link I read is the neuritis may fade away but may take 2-3 yrs...

I would get a second opinion by another top surgeon if possible..
this is your life and sticking with the same surgeon only- might leave you open to another or better options being missed completely.

Post op your pain level was only 2-3 ? was that with meds or no meds?

Usually most here will suggest to consider surgery as last resort , like extremely high pain, if clots are major factor, or a extra rib or bony issue..

I would really suggest seeing a top TOS surgeon for second opinion...to get the very best of care..especially since it may be a second go around.. not a time to take chances or jump into another surgery.
