What is the reason for facial stiffness?

Facial muscle stiffness may be caused by facial paralysis. In addition, stroke hemiplegia or trigeminal neuralgia can also cause similar symptoms. Facial paralysis refers to the motor dysfunction of facial expression muscle, which will lead to local muscle spasm or neurological dysfunction, central facial neuritis, facial expression muscle paralysis and muscle stiffness. Hemiplegia can also cause this symptom, which is caused by acute vascular disease, which will lead to facial nerve disorder, even movement disorder, resulting in low muscle tension and facial muscle stiffness. If the microvasculature of facial trigeminal nerve is compressed, it will cause trigeminal neuralgia, lead to facial expression muscle spasm, and then lead to muscle stiffness, accompanied by symptoms of local pain, which needs timely treatment.
