Neck pain when angry may be related to the following factors: 1. Elevated pressure in the cerebrospinal fluid. Patients will have an increase in blood pressure when angry, which may later lead to an increase in intracranial pressure. Since the cerebrospinal fluid inside the brain is connected to the cerebrospinal fluid inside the spinal cord, it will lead to a corresponding increase in pressure in the spinal canal at this time. If the patient has some previous occupancy in the spinal canal, like a protruding disc, this may lead to these occupancy factors, which may produce more serious compression on the spinal cord or nerve roots and produce neck pain. 2. muscle spasms, when the patient is angry, there may be involuntary muscle spasms throughout the body, or there is a fixed in a certain posture, which will lead to muscle spasms in the neck, and then cause pain.
