Twitching Right Thumb Causes

Your lifestyle, including your diet and exercise routine,  can contribute to some causes of twitching in your right thumb. Others are caused by conditions that may have affected your nervous system. Below are some of the causes of twitching right thumb

1. Lack of sleep

Neurotransmitters can accumulate in your brain nerves if you don’t get enough sleep, which can cause twitching of your right thumb.

2. Drug overdose

The use of stimulants can cause the right thumb twitching. Drug overdoses can include both dangerous stimulants like cocaine or amphetamines as well as substances that are perfectly safe when consumed in moderation, such as caffeine or over-the-counter energy drinks.

3. Cramp-fasciculation syndrome (CFS)

CFS is a muscle condition known as benign fasciculation syndrome, which causes your muscles to cramp and twitch because of overactive nerves.

4. Exercise

Exercise is another cause of twitching in the right thumb, especially intense exercises like lifting weights or running. It occurs when your body doesn’t have enough oxygen to convert lactate(a metabolic substance) into energy. The muscles retain extra lactate, which can cause muscle contractions.

5. Central nervous system causes

Conditions of the central nervous system, such as Parkinson’s disease, myopathy, spinal muscular atrophy, amyotrophic lateral sclerosis (ALS), and nerve injury (neuropathy), can cause twitching of the right thumb.

How to Prevent Right Thumb Twitching?

If you pay attention to some common preventive measures, you can prevent your right thumb twitching. Some of the causes of thumb twitching can be prevented by using the following methods:

1. By Eating a Healthy Diet

You should consume enough vitamins, including B-6, B-12, C, and D, and at least 65 ounces of water daily. You won’t have to worry about thumb twitching if you eat healthy diets and stay hydrated.

Stress and anxiety can cause twitching of your right thumb by contracting your muscles. However, Meditation and breathing exercises can help reduce twitching caused by stress.

Why Is My Right Thumb Twitching Uncontrollably?

Exercise and overuse, which often go hand in hand, are the leading causes of benign muscle twitching. Simply put, the nerves get overworked and stay in a residual excited state.

Is There A Difference Between Right And Left Thumb Twitching?

We conducted extensive research, including clinical studies, medical records, patient interviews, etc. Still, we could not find any references to the left thumb twitching being worse than the right thumb.

Therefore, the only conclusion is that there is no medically relevant difference between the two; instead, it all comes down to different patients. Some patients notice thumb twitching on the right side, while others notice it on the left. So, Why do people ask this question? It could be because 10% of the population is left-handed. Thus, people tend to become more worried when the left thumb begins to twitch.
