If you are pretty sure that the laptop/couch combo started this, then I don't think you really need to find a surgeon yet.

I don't know if the PT you went to was highly skilled or especially talented.

Did they check your top rib/rib mobilization?
Trigger points manual release?
overall posture assessment?
do you have a better computer set up now? so not to make sx worse?

You might focus on seeking out expert body workers, advanced PT or even a chiro that has many skills/talents and does soft tissue work. Mine did and he was the most help for my version of TOS (chronic multiple RSI type)

There are many things you can do at home to repair the posture and soft tissue restrictions. Youtube is full of so many therapy types, posture assessments, you can get an idea of what might be best or who to look for.

Since you are so from a large town , I would suggest exploring Sharon Butler's website and possible getting her TOS plan (does have a 100% guarantee) www.selfcare4rsi.com
she suggests very gentle stretching to loosen the sticky tissues..
her articles are very good -
