Hi honey - you have a lot going on.
I'm new here too and all I can address is the PN which I had for years before I sought help. (long story)
All I can share with you is this - I get a lidocaine infusion once a month and I'm almost pain free. I also take gabapentin 3 times a day. It's been 2 years now since I asked God to take me, that's how bad the pain was then.
Lidocaine really was the answer for me where the PN was concerned.
