Welcome Sharna,
I think there is quite a bit of hope in here and some options for more information and improvement. I second the chiropractic consult. You never know what they might find. I have a trick rib that subluxes with some regularity and causes a lot of pain and inability to take a breath. My chiro does a quick, painless adjustment and I am good for another few months or year.
Also on nerve entrapement....I too am a nerve entrapment surgery patient. I have also had nerve ultrasound that found swelling of the nerve and I had a carefully done US guided injection of steroid to "bathe" the nerve as treatment (this was after surgery when things were swollen in general and mechanics of my ankle were tugging on the nerve and it was miserable) NCS WILL NOT indicate nerve swelling. Conduction may look perfectly fine in a nerve that has enough swelling to get stuck trying to slide through its tunnel and is aggravated. Your normal NCS does not rule out the utility of treating the nerve by a skilled PMR who can do that injection. If you do not have improvement with PT and altered activity it is worth revisiting the ultrasound and seeing if you need to do anything. It just may break the cycle and allow healing, mine did!
