Congenital Insensitivity to Pain (CIP)

Congenital insensitivity  to pain (CIP) is characterized by the inability to experience inflammatory, heat, or visceral pain sensations. All other sensory, motor, and autonomic functions are normal. Affected individuals have typically exhibited bone deformities and neuropathic joints secondary to untreated injuries, self-mutilating oral and extremity lesions from biting, and a history of burn-related injuries. They also experience anosmia or hyperosmia but have normal blood pressure, tear formation, sweating, and body temperature regulation.
