Brief Answer:
Majority of cases its nothing serious. But do consult a physician

Detailed Answer:
Hello Dear. Muscle twitching is also called muscle fasciculation. Twitching involves small muscle contractions in the body. Your muscles are made up of fibers that your nerves control. Stimulation or damage to a nerve may cause your muscle fibers to twitch.

Most muscle twitches go unnoticed and aren’t cause for concern. In some cases, they may indicate a nervous system condition and you should see your doctor.

Common causes of muscle twitching include the following:

1. Twitching can occur after physical activity because lactic acid accumulates in the muscles used during exercise. It most often affects the arms, legs, and back.

2. Muscle twitches caused by stress and anxiety are often called “nervous ticks.” They can affect any muscle in the body.

3. Consuming too much caffeine and other stimulants can cause muscles in any part of the body to twitch.

4. Deficiencies of certain nutrients can cause muscle spasms, particularly in the eyelids, calves, and hands. Common types of nutritional deficiencies include vitamin D, vitamin B, and calcium deficiencies.

5. Dehydration can cause muscle contraction and twitching, especially in the body’s larger muscles. These include the legs, arms, and torso.

6. The nicotine found in cigarettes and other tobacco products can cause muscle twitching, especially in the legs.

7. Muscle spasms can occur in the eyelid or the area around the eye when the eyelid or the surface of the eye is irritated.

8. Adverse reactions to certain drugs, including corticosteroids and estrogen pills, can trigger muscle spasms. The twitching may affect the hands, arms, or legs.

These common causes of muscle spasms are usually minor conditions that easily resolve. The twitching should subside after a couple of days.

However, you should talk to your doctor if you suspect that your medication is causing your muscle twitching. Your doctor may recommend a lower dosage or switch you to another medication. You should also contact your doctor if you believe you have a nutritional deficiency.

While most muscle twitching is the result of minor conditions and certain lifestyle habits, some muscle spasms can be triggered by more serious causes. These disorders are often related to problems with the nervous system, which includes the brain and spinal cord. They may damage the nerves connected to your muscles, leading to twitching. Some of the rare yet serious conditions that can trigger muscle twitches include:

1. Muscular dystrophies are a group of inherited diseases that damage and weaken the muscles over time. They can cause muscle twitching in the face and neck or hips and shoulders.

2. XXXXXXX Gehrig’s disease is also known as amyotrophic lateral sclerosis. It’s a condition that causes nerve cells to die. The twitching can affect the muscles in any part the body, but it usually occurs in the arms and legs first.

3. Spinal muscular atrophy damages the motor nerve cells in the spinal cord, affecting the control of muscle movement. It can cause the tongue to twitch.
Isaac’s syndrome affects the nerves that stimulate muscle fibers, resulting in frequent muscle twitching. The spasms most often occur in the arm and leg muscles.

Muscle twitching typically isn’t an emergency, but a serious medical condition may be causing it. Make an appointment with your doctor if your twitching becomes a chronic or persistent issue.
