Facial spasms are an early indication of tetanus, often appearing at the same time as spasms in the jaw. This symptom is a result of the infection and its effect on the nervous system; you may also experience spasms in the neck area. People around you may say that your facial expressions appear unnatural. Sometimes, the spasms in the face can cause a rigid grin called risus sardonicus. If you notice any changes in your facial muscles, contact your hospital as soon as possible. After this initial stage, symptoms are likely to worsen if the affected does not seek medical attention.
