AbstractPain hyperacusis, also known as noxacusis, causes physical pain in response to sounds that do not bother most people. How sound causes excruciating pain that can last for weeks or months is not well understood, resulting in a lack of effective treatments. To gain insight into the underlying mechanisms of the condition, 32 adults attended a virtual focus group to describe their sound-induced pain. Focus group data were used to develop three follow-up surveys that aimed to identify the most common symptoms of pain hyperacusis as well as the participants' use of therapies for pain relief. All participants endorsed negative effects of pain hyperacusis on psychosocial and physical function. Most reported sound-induced burning (80.77%), stabbing (76.92%), throbbing (73.08%), and pinching (53.85%) sensations that occur either in the ear or elsewhere in the body. Participants have used numerous pharmaceutical and non-pharmaceutical interventions to alleviate their pain with varying degrees of pain relief. Benzodiazepines and nerve blockers emerged as the most effective analgesic options while non-pharmaceutical therapies were largely ineffective. Symptoms and therapeutic approaches were generally consistent with peripheral mechanistic theories of pain hyperacusis (e.g., trigeminal nerve involvement). An interdisciplinary approach to clinical studies and the development of animal models are needed to identify and treat the pathological mechanisms of pain hyperacusis. PERSPECTIVE: This article presents the physical and psychosocial consequences of debilitating sound-induced pain (i.e., pain hyperacusis) and the interventions that sufferers have sought for pain relief. The results are largely consistent with peripheral mechanistic theories (e.g., trigeminal nerve involvement) and will guide future work to investigate neural mechanisms and effective therapies.Copyright © 2024.
