Evidence for pain and recovery is condition-specific rather than proof that red light treats pain generally.

Trials differ in diagnosis, wavelength, dose and treatment location. A pooled positive result can hide many incompatible protocols.

Do not let symptom relief hide a diagnosis

Persistent or severe pain needs appropriate assessment; light should not delay investigation of injury or disease.
