1. Apparatus comprising:
a first electrode, configured to be implanted at a first anatomical site in a nucleus pulposus of an intervertebral disc of a subject;
a second electrode, configured to be implanted at a second anatomical site outside the nucleus pulposus of the disc; and
a control unit, configured to:
detect a pressure difference between the first and the second anatomical sites by detecting a streaming voltage between the first and the second electrodes, and
in response to the detected pressure difference, drive fluid between the nucleus pulposus and outside the nucleus pulposus by applying a treatment voltage between the first and the second electrodes.
