As someone that battled with neuropathy, I highly suggest that you go see a specialist regarding circulation. It could be from diabetes, or another condition, but the pain you're feeling is your nerve ends not getting enough blood flow and dying. Masking the pain is great I suppose. But you'll be bummed when you don't have the pain, but don't have feeling either. You can stop the advance of the problem while managing the pain. Don't just do the latter.
That's my advice. As always, do with it as you will.
