1. A device for monitoring pain of a user, comprising:

  • a receiving unit configured to receive an accelerometer signal from an accelerometer sensor configured to be worn in use by the user, wherein the accelerometer signal from the accelerometer sensor comprises components of a pulse signal and components of a respiration signal; and

    a processing unit which is configured to;

    derive the instantaneous pulse signal and the respiration signal from the accelerometer signal;

    adapt the pulse signal based on the respiration signal in order to obtain a corrected pulse signal; and

    derive a pain descriptor based on the corrected pulse signal.
