There is one simple mechanical test for nerve compression at the wrist and foot... It is called Tinel's sign.

If you don't have it strongly, you probably don't have compression at the wrist.

I have carpal tunnel, which now after having my thyroid supplemented is much better, but not totally 100% gone.
There are times I can extend my fingers doing something and still a huge zing like an electric shock. If you've never had that
feeling either at the doctor's when tapped or when doing something, your nerve compression may be at the neck level.
Tinel's of ankle:

You can also tap the top of the instep with a wooden spoon and
see if compression there (often from shoes tied too tightly) affects the toes.

For example I have minor Tinel's at the lateral ankle, but a strong one on the top of the instep. So I use an alternate shoe lacing pattern to take the pressure off at that location.

These examination may help locate where your nerve impact is located.
