[partial rib restructuring both sides and the left minor pectoral muscle detached]

How long ago was your surgery/s?
Why partial rib and not all the rib?

[nerve goes through my muscles like spaghetti]
This might be the main cause, but something else must be a factor for the increase in pain.
the rib stump rubbing or regrowing?
and scar tissue increasing?

Might be worth a second look/opinion with a TOS dr.
