I think Alison covered most of it very well

I think looking around and finding the best {and knowledgeable} docs, PT, DC {if so inclined}, bodyworker etc - is a good way to go.

Until the neuro doc is found, tests done and decided upon-

Can your primary doc find a really good {expert/knowledgeable/skilled BP/neuro} PT so you can get started - but of course if you get into it and think it not going well -stop!
Or maybe you can track one down and ask Dr to rx the PT??

It really is amazing what a highly skilled and knowledgeable PT, DC, or DO {RLNP} can do - with the tools of LLLT {laser}, INF stim, Ultrasound and some manual triggerpoint.

But I am wondering if -as your Dr thinks -about the scar tissue, as the timeline is about right.
[(2) try not to worry too much about this because if symtoms resolved completely for seven months then nerve is likely in very good condition. Probably inflammation or scar tissue secondary to muscle injury causing nerve irritation or compression. (I don't know how much credibility to put into this advice, but he is quite a good doctor in my past experience),]
