Abstract
In 1965, Pat Wall (who died August 8, 2001) and Ron Melzack published their paper in Science, entitled a ‘New Theory of Pain’.1 Despite the mention that it was a theory, endless arguments and debates ensued. Poring over the details, arguing over the substrates, all futile and pointless since the theory has stood the test of time and has changed the way we think about pain—the new theory has endured.
