These drugs can be successful in treating mild cases but cause side effects (e.g., drowsiness, unsteadiness, nausea, skin rash, dependence). Muscle relaxants such as baclofen (Lioresal), diazepam (Valium), and clonazepam (Klonopin) may also be prescribed. Your doctor may prescribe anti-convulsant drugs such as carbamazepine (Tegretol) or phenytoin (Dilantin) to block firing of the nerve. An EMG is often done along with a nerve conduction velocity (NCV) study to measure your muscle and nerve electrical activity. Next, you may have an electromyogram ( EMG) study of the face. An MRI scan may be ordered to rule out other conditions such as a brain tumor, aneurysm, or AVM that may be causing facial nerve compression. How is a diagnosis made?įirst, your doctor will carefully review your medical history and perform a neurological exam. The average age of onset is 44 years and occurs slightly more in women. Hemifacial spasm is rare, affecting only 8 people in 100,000 in the US. Both hemifacial spasm and trigeminal neuralgia are caused by nerve compression from a blood vessel, yet differ in whether the sensory nerve or motor nerve is compressed. This condition is related to trigeminal neuralgiaan irritation of the fifth cranial nerve that causes severe facial pain. The compression causes the nerve to misfire making your facial muscles contract. The most common cause is compression of your facial nerve by the anterior inferior cerebellar artery where the nerve begins at your brainstem. Hemifacial spasm can be caused by injury to the facial nerve, a tumor or blood vessel compressing the nerve, or Bells palsy. The twitching is usually not painful, but it can be embarrassing and interfere with normal expression and vision. In the other 8% it starts near the chin and progresses upward. In 92% of cases, the spasm starts near the eye and img-fluidn the face over time. The facial nerve originates in the brainstem and exits the skull beneath the ear where it has five main branches that control the muscles of facial expression. (Taking it with calcium decreases this side effect.) When taking calcium and magnesium supplements together, the typical ratio is two parts calcium to one of magnesium.Figure 1. Keep in mind that for many people, 500 mg of magnesium can cause loose stools or diarrhea. Start with 200 mg of magnesium a day (use citrate, glycinate, or chelate forms) and slowly increase the dose toward 500 mg a day until you notice a difference. Both minerals are key to healthy neurological function and muscle control. Here, the solution is simply to increase your dietary intake of foods containing these nutrients or by taking supplements. Other possible causes are magnesium or calcium deficiencies, which your doctor can determine with a blood test. Dehydration can also cause twitching in the legs, arms and torso. If you’re taking one of these or any other medications, ask your physician or pharmacist if twitching is a side effect. Stress, anxiety, fatigue and too much caffeine can also play a role as can a number of prescription drugs (including diuretics, corticosteroids and estrogens). In general, twitching elsewhere in your body tends to occur when you’re tired or after you’ve been exercising strenuously. See a doctor if it doesn’t go away within a few weeks or if you experience drooping eyelids, or redness or swelling of the eyes or if the twitching also occurs on your face or other parts of the body. It can be triggered by bright light, alcohol intake, too much caffeine, fatigue, smoking, stress, and irritation of the surface of the eyes or inner eyelids (as by wind, dust, or smog). Eyelid twitching usually goes away quickly but tends to recur.
