I don't expect much for numbness. But you can never tell.
If the numbness is because the nerves are "dead"... that will be it.

But I have transient numbness in my hands (carpal tunnel) and feet, which comes and goes depending on compression issues.
Too tight shoes =numbness
gripping the steering wheel for long periods and my hands go numb. Some gloves will make my hands numb too.

So for this transient type, perhaps this type is more "inflammatory" etc, and may respond to the Precise.
I have more pain and burning than numbness overall.

The Zonalon might work for numbness since it is a TCA.
I'd try it if I were you, Echoes. I hope you have insurance as it is very expensive (over $100 for 1.5oz generic cash). I would think you'd know something by the end of one tube.

BTW I was checking my WalMart receipt to make sure I got all my bags...you know that spinning gizmo that keeps some of your purchases sometimes????....anyway my Precise cream rang up at 6.97! (the shelf tag was 7.97 and so is the price tag). Don't know why.
