Post electric shock syndrome describes the circumstance where a person's post-traumatic response to having suffered a shock results in neuropsychological and neuropsychiatric conditions that interfere with the victim's ability to resume his or her normal life, such as not being able to return to work.
Can electric shock cause nerve damage?
Can electric shock cause nerve damage? Electric shock can cause nerve damage. As electrical current passes through a person's body, the person's nerve tissue is unable to resist the current, causing tissue to be damaged. Nerve damage can also cause a person to suffer pain, tingling, numbness and weakness.

What happens when you get an electric shock?
An electric shock occurs when a person comes into contact with a power source, causing energy to flow throughout their body. Depending on the type and level of electrical current, electrical shock injuries can range from mild to serious. Extremely high voltage shocks can result in electrocution, which is death due to cardiac arrest.
What is the most at risk industry for electrical accidents?
While anyone can suffer an electrocution injury at work, construction workers run the highest risk of any industry. According to the Occupational Safety and Health Administration (OSHA), 53% of workplace electrical fatalities occur in construction. This industry is comprised of roofers, carpenters, and laborers, but the most at-risk construction workers are electricians, who account for over half of electrical injuries suffered in the field.
What to do if you have an electrical shock?

Patients with a low voltage exposure and unremarkable exam do not need any further testing.
Can electrical currents cause thermal injury?
Electrical currents may cause thermal injury or physiological effects. The amount of current that flows through the body is the most important factor in determining injury – this will depend upon the voltage and resistance (recall V = IR), and is influenced by the following factors.
Is AC or DC more dangerous?
Type of current: electrical currents may be alternating current (AC) or direct current (DC), with AC being more dangerous than DC. DC results in a single muscle spasm, whilst AC may produce tetanic contractions that prevent the victim from letting go of the source, thereby increasing the duration of exposure.

What is electrical burn?
Electrical burn. Electric burn usually corresponds with a moderate or severe electric shock. The strength of the current determines the extent to which electrical burns occur. Apart from burning the superficial part of the skin, electric burn cause a lot of damage to the body’s internal parts. Avoid handling naked electric wires and appliances.
What determines the extent of harm caused?
An electric current runs through the body, and the current’s strength determines the extent of harm caused. Therefore, water and the current strength are the main factors that determine the extent of the harm it courses.
Can electrical fires harm you?
Electric fires may not directly harm you, but the fire is vibrant and gets easily propagated by furniture and other items in the house. Many people have lost their lives because of electrical fires. Therefore, make sure that you alert an electrician earlier whenever you note a faulty live wire lying around.

Some key factors in the severity of any electrocution injury are the voltage of the current, the path the current took through the body, and the length of time the body was in contact with the current.
What happens if you get exposed to electricity?
At the moment of an electricity exposure injury, the respiratory and cardiovascular systems are at the greatest risk for damage. Electric shocks can disrupt heart action or completely paralyze the respiratory system, resulting in the cessation of breathing, and death. And in addition to burns (which can run the gamut in terms of severity) electricity exposure injuries can cause much more harm to the body that may not be as visible, including damage to internal organs, muscles, and tissue.
