Multi-sensory/Poly-sensory Hypersensitivity in Fibromyalgia
Multi-sensory hypersensitivity is a well-established clinical pattern found in many fibromyalgia patients whereby they are over sensitive to two or more sensory modalities such as somatosensation (especially tactile allodynia) and sound. The over-sensitivity is aversive in nature whereby the stimuli are uncomfortable or painful. The usefulness of the term lies in its value in drawing attention that in these patients, there is an issue that cuts through any one sensory system of the brain. These over-sensitivities involve central sensitization, which is viewed as a primary underlying aspect.
