WebMechanisms Supporting SIH Hyperalgesia can be associated with potentiated adrenergic sensitivity of primary afferent fibers as a result of up-regulation of α 2 -adrenergic receptors and exacerbation of neurogenic inflammation by α 1 -adrenergic receptors. By contrast, exposure to prolonged/chronic stress or future-oriented anxiety or depression generally leads to hyperalgesia i.e. an exacerbation of pain, referred toas stress-induced hyperalgesia (Rhudy& Meagher, 2000).
