A number of possibilities, all of which require evaluation by a neurologist or other specialist. Please get her to see a doctor as quickly as possible, because the most dire possibilities include bleeding in the brain, compressed nerves/nerve roots in the cervical spine, etc.

Hi there. Muscle twitches are caused by tiny contractions inside the muscles usually due to involuntary firing of nerves inside your muscles and can lead to muscle weakness.
certain possible causes of muscle twitches are  muscle fatigue, anxiety, certain medicines, caffeine, stroke, multiple sclerosis, trauma to the nerves and nervous system disorder. It may be seen in association with fibromyalgia syndrome. This need to be investigated by a neurologist and treatment would depend on the diagnosis. Certain stretching and exercise, massaging the affected muscle, medicines like klonopin may help stop the twitches and spasms. Nutritional supplements and physiotherapy may help in relevant cases. Hope this helps. Take care.
