Chronic pain and pain relief by extracorporeal shock wave therapy

To the Editor: My paper: A neural model for chronic pain and pain relief by extracorporeal shock wave treatment (Urol Res (2008) 36:327–334) [1] provoked a vigorous offence by Ch. Schmitz and DePace (Letter to the Editor: Pain relief by extracorporeal shockwave therapy: an update on current understanding, Urol Res (2009) 37:231–234) [2] which requires a clarifying reply.
