Why Does Chronic Back Pain Make Everyday Sounds Feel Harsher?
People with chronic back pain process everyday sounds differently, and more intensely, than people without pain, according to new research. The study is one of the first to tie this sound hypersensitivity to specific, measurable changes in the brain, indicating that chronic back pain affects far more than the back. The researchers compared self-reported and neural responses in 142 adults with chronic back pain relative to 51 pain-free controls. All participants, including controls, underwent brain imaging.
