Muscle fasciculation; Fasciculations of muscle

There is usually no treatment necessary for benign muscle twitching.

Call your health care provider if you have long-term or persistent muscle twitches.

Your health care provider will take a medical history and perform a physical examination.

Medical history questions may include:

• When did you first notice the twitching?
• How long does it last?
• How often do you experience twitching?
• What muscles are affected?
• Is it always in the same location?
• Are you pregnant?
• What other symptoms do you have?

Diagnostic tests vary depending on the suspected cause. Tests may include:

• Blood tests to look for problems with electrolytes, thyroid gland function, and blood chemistry
• Electromyogram (EMG)
• Nerve conduction studies
• MRI of the spine or brain
