Muscle twitching

Meaning muscle twitching

Muscle twitching is a sudden, involuntary contraction and relaxation of a muscle. Common examples of muscle twitching include waking up with a start while sleeping, muscle twitching after exercise, or when stressed .

Muscle twitching

Patients will experience sudden twitching, shaking, or tensing of muscle fibers or small single muscle groups. Most often, it occurs in one area, but sometimes it can occur all over the body at once. If the symptoms are severe, it may affect eating, speaking, or walking.

Muscle twitching is usually temporary and disappears on its own within a few days. However, if the symptoms become more frequent, are continuous, or if there are other symptoms in the area where the twitching occurs , such as numbness, muscle weakness, or muscle atrophy, you should see a doctor to find the cause and receive proper treatment, as it could be a sign of another disease.

Causes of muscle twitching

Common muscle twitching symptoms are usually harmless and are caused by everyday activities, such as:

• Muscle twitches after exercise are caused by lactic acid, a waste product of energy metabolism, being stored more during exercise, causing frequent twitches in the arms, legs, and back.
• Muscle twitching from stress and anxiety causes nervous system disorders (nervous ticks) that can occur in any part of the body.
• Excessive intake of caffeine and other stimulants can cause muscle twitching in all parts of the body.
• Malnutrition and vitamin deficiencies, such as vitamin D, vitamin B, or calcium, mostly cause muscle spasms in the eyelids, calves, and hands.
• Dehydration and electrolyte deprivation cause muscle contractions and twitching, often affecting large muscles such as the legs, arms, or trunk.
• Nicotine, found in cigarettes and other addictive substances, makes your leg muscles twitch more easily.
• The use of certain medications, such as corticosteroids and estrogen pills, can easily cause muscle twitching in the hands, arms or legs. Therefore, you should inform your doctor to request a new type of medication or a lower concentration of the medication.

However, some patients who experience frequent twitching may be the result of a neurological disease or disorder, such as muscular dystrophy, amyotrophic lateral sclerosis/Lou Gehrig’s Disease ( ALS ), spinal muscular atrophy (SMA), or Isaac’s syndrome.

Diagnosis of muscle twitching

In the first step, the doctor will ask about the patient’s medical history and details of the muscle twitching symptoms, such as when they occurred, how long and how often they occurred, the area where the symptoms occurred, whether or not they were pregnant, and other abnormalities. Then there will be a general physical examination and other additional examinations. The doctor will consider the patient’s health risks and the possible causes, such as:

• Blood tests to check for abnormalities in blood electrolytes, thyroid function, and other chemicals in the blood.
• A computerized tomography ( CT ) scan of the spinal cord and brain.
• Electromyography (EMG)
• Nerve Conduction Studies
• Magnetic resonance imaging ( MRI ) scan of the spinal cord or brain.

Diagnosis will help the doctor find out the real cause. Persistent or recurring muscle twitching is often caused by an underlying disease or disorder. Early detection will allow for effective treatment and reduce other long-term health problems.

Treatment of muscle twitching

Muscle twitching usually does not require treatment because the symptoms gradually decrease and disappear within 2-3 days. However, in cases where muscle twitching is severe, the symptoms may be improved with medication.

Examples of drug groups used to treat muscle spasms

• Corticosteroids, such as betamethasone and prednisolone
• Muscle relaxants such as carisoprodol, cyclobenzaprine
• Neuromuscular blockers, such as botulinum toxin type A, botulinum toxin type B
• Tranquilizers, such as clonazepam

Complications of muscle twitching

Muscle twitching is a symptom that does not cause any complications. However, for those who have frequent symptoms and let it become chronic without finding the cause and completely curing the symptoms, it may cause the underlying disease to not be treated, such as epilepsy, low electrolyte levels, which will lead to other long-term health problems from the disease itself.

Prevention of muscle twitching

Muscle twitching may not be completely preventable, but you can reduce your chances and risks by following these tips:

• Eat a nutritious diet, focusing on vegetables, fruits, grains, and lean meats such as chicken or tofu.
• Get enough sleep, at least 6-8 hours, to allow your body and nerves to recover.
• Try to reduce stress by doing activities you enjoy or exercising.
• Limit the amount of caffeine you consume from beverages or food to a moderate amount per day, as caffeine can trigger muscle spasms.
• Smoking should not be done because nicotine is a stimulant that may affect the functioning of the nervous system and cause other health problems.
• People who take certain medications and experience muscle twitching, such as amphetamines, should consult a doctor to request a replacement medication.
