Chronic back pain may heighten sensitivity to unpleasant sounds, study finds
A study published in Annals of Neurology found that people with chronic back pain rate unpleasant sounds more intensely and show stronger activity in auditory and emotion-processing brain regions than pain-free individuals. The findings suggest a broader, multi-sensory amplification linked to chronic pain, possibly via a shared brain mechanism. Pain reprocessing therapy (PRT) produced modest improvements in pain and reduced unpleasantness of low-intensity sounds, but the evidence isn’t yet robust, and researchers call for more work to understand if this hypersensitivity extends to other senses and to confirm causality.
