The past decade has seen great progress in
understanding its causes and in finding new drugs that promise great benefit. An early outcome of the
research has been the observation that the new drugs do not blunt normal pain sensation--a
pattern beginning to find explanation through the realization that neural pain circuits rewire
themselves, both anatomically and biochemically, after nerve injury.
