Has there been a moment when you simply brushed against someone and unexpectedly received a slight electric shock? It doesn’t hurt, yet it feels unpleasant enough to make you pull back your hand.

What are these sensations?
These shocks, though technically not electric, are sudden, brief feelings of sharp, tingling, or burning pain. Those who get it, often describe it as a small jolt of electricity running through their body. These sensations can take place suddenly, or after certain movements, and can occur multiple times in a day, usually occurring for a few seconds, though they might be longer.
Often, these feelings indicate an issue with your nervous system. The nerves communicate messages between your brain and body; once they become impaired or inflamed, they might transmit odd signals, such as tingling sensations akin to electric jolts.
Possible causes
Several factors can cause individuals to experience electrical sensations, such as:
Nerve damage: Conditions like sciatica or pinched nerves, can be responsible for these electric shocks, and that too sudden.
Injuries: Physical injuries to the spine or nerves.
Deficiencies of vitamins: They might differ, however, a major cause is often pointed out as vitamin B12 deficiency.
Long-term ailments: These encompass diabetes, infections, or even adverse reactions to certain medications.
Multiple sclerosis (MS) is a progressively neurologic disorder impacting the nerves within both the brain and spinal cord.
Let’s delve into how a lack of Vitamin B12 might lead to those ‘shocking’ sensations.
The significance of Vitamin B12
Vitamin B12 is a nutrient present in animal-based foods such as meat, eggs, and dairy items. This vitamin is crucial for numerous bodily functions, which include:
Producing fresh red blood cells.
Maintaining the well-being and proper operation of the nervous system
Helping DNA production.
Supporting brain function.
When lacking sufficient Vitamin B12, your body cannot produce healthy nerve cells. Consequently, this may result in nerve damage and manifestations such as electric shock-like sensations.

Investigating the connection between vitamin B12 deficiency and electrical sensations
As mentioned earlier, if you lack sufficient Vitamin B12, your nerve cells might suffer damage or cease functioning correctly. This situation is referred to as neuropathy. When nerves sustain harm, they could transmit incorrect messages to the brain, leading to sensations such as tingling, numbness, or sharp jolts of pain.
A particular symptom associated with vitamin B12 deficiency is known as Lhermitte’s sign. This manifests as an abrupt sensation akin to an electric shock that travels through the spine and limbs upon flexing the neck forward. Such occurrences happen because the myelin sheath, which protects nerve fibers, gets compromised from insufficient levels of Vitamin B12.
Who is at risk?
Even though anybody can experience a deficiency in Vitamin B12, certain individuals may face this issue more frequently.
Vegetarians (since B12 is mostly in animal foods).
Older adults (because as we age, our bodies absorb B12 less efficiently).
Individuals who suffer from digestive conditions such as Crohn’s disease or celiac disease.
People who have undergone stomach or intestinal surgery.
Individuals who are on medication that impacts B12 absorption.
What should you do?
Should you encounter tingling from an electrical sensation, particularly when accompanied by numbness, weakness, or issues with balance, consult a physician promptly. They might conduct nerve examinations if necessary and could also verify your vitamin B12 status.
Treatment for Vitamin B12 deficiency involves either supplements or injections. Early intervention can lead to improvement in nerve damage and alleviate electric shock sensations.
