Hemifacial Spasm (HFS)

Symptoms and Signs of Hemifacial Spasm (HFS)

The symptoms of hemifacial spasm usually begin with an eyelid twitching. Eventually, the eye may be forced to close. If contractions spread to the lower face, the mouth may be pulled to one side. As the disorder develops, spasms may constantly affect all muscles on one side of the face.
