Electrical Burn

Overview

An electrical burn is an injury caused when an electric current passes through the body. The current can burn skin where it enters and leaves, and it can also harm muscles, nerves, the heart, and other organs that you cannot see from the outside. Even a small-looking mark can hide a more serious injury.

Electrical burns are much less common than burns from hot water, fire, or chemicals, but they can be serious. Many happen at home or at work.

Anyone can be affected. Young children are at risk from sockets and cords. Electricians, builders, farmers, and other workers can be exposed on the job. Older adults and people with heart problems or implanted devices such as pacemakers may be more vulnerable to heart rhythm problems.

Symptoms

Common symptoms

• Burns or marks where the current entered and left the body, though there may be no visible mark
• Pain, numbness, tingling, or weakness in the affected area
• Muscle twitching, stiffness, or trouble moving a limb
• Dizziness, headache, confusion, or feeling faint
• Fast, slow, or uneven heartbeat, chest pain, or shortness of breath
• Burns to the mouth or hands, especially in children
• Feeling anxious or shaken after the shock

Symptoms in children

• Burns at the mouth, lips, or tongue from biting or sucking a cord
• Burns on the hands or fingers from touching a socket or appliance
• Crying, fussiness, poor feeding, or drooling
• A limb the child will not use or moves with pain
• Confusion, sleepiness, breathing problems, or a fast or uneven heartbeat
• No visible mark even after a shock, which still needs medical advice

Symptoms in older adults

• Confusion, dizziness, weakness, or a fall may be the main sign
• Chest pain, palpitations, or breathlessness
• Burns that look small but are deeper because skin is thinner
• Slower healing and higher risk of infection
• Existing heart conditions or implanted heart devices can make heart rhythm problems more likely

Causes

Main causes

• Touching faulty appliances, damaged cords, exposed wiring, or broken sockets
• Putting objects or fingers into electrical outlets, especially by children
• Contact with overhead power lines, railway power supplies, or industrial machinery
• Lightning strikes
• Doing DIY electrical work without proper training
• Using electrical items near water or with wet hands
• Touching a person or object that is still connected to electricity

Risk factors

• Being a young child with easy access to sockets and cords
• Working with electricity, machinery, or power lines
• Damaged insulation, old wiring, or missing safety switches
• Wet conditions or wet skin
• Wearing metal jewellery or watches that can conduct current
• Having a heart condition or an implanted heart device
• Being pregnant
• Using alcohol or drugs that affect judgement around electrical work

When to see a doctor

See a doctor urgently if:

• After any electrical shock with a burn or visible mark
• If you feel dizzy, confused, sick, or have chest pain or palpitations
• If you have numbness, tingling, weakness, or trouble moving a limb
• If the shock came from a socket, appliance, power line, or lightning
• If a child, pregnant person, or older adult has had a shock
• If you have a heart condition or an implanted heart device and have had a shock

Book a routine appointment if:

• If a minor burn is healing but you have ongoing pain, scarring, or stiffness
• If you feel anxious, have nightmares, or avoid electricity after the shock
• If you have questions about wound care or returning to work or sport
• If you notice signs of infection such as increasing redness, swelling, warmth, pus, or fever

Diagnosis

A doctor or nurse will ask how the shock happened, what the power source was, how long contact lasted, and whether you have any symptoms. They will check your breathing, heart, skin, nerves, and muscles, and look for entry and exit marks. They may watch your heart and do tests to look for hidden injury.

Tests that may be done

• Physical exam and wound check
• ECG, a heart tracing, and sometimes heart monitoring
• Blood tests to check muscle damage, kidney function, and general health
• Urine tests to look for muscle breakdown
• X-rays, CT scans, or MRI scans if deeper injury or fractures are suspected
• Checks of nerve and blood vessel function in the affected limb

What to expect at your appointment

You may need to stay in hospital for observation, especially after a high-voltage shock or if you have heart symptoms. Tests may be repeated over a few hours. Bring any details you know about the electrical source and whether the power was turned off. If you feel well, tell the clinician, but let them decide when it is safe to go home.

Treatment

Treatment starts with making the scene safe and calling for emergency help if needed. The main goals are to check for hidden injury, protect the heart and other organs, care for burns, control pain, and prevent infection. Serious electrical injuries are treated by a specialist team.

Self-care at home

• Only care for the burn at home if a clinician has checked you and said it is safe
• Keep the wound clean and covered with a clean, non-stick dressing as advised
• Do not apply butter, toothpaste, oils, or ice to a burn
• Do not burst blisters
• Take care to avoid another shock and do not use damaged electrical items
• Follow up as instructed and return if redness, swelling, pus, or fever develops
• Rest and avoid driving or heavy work if you feel dizzy, weak, or shaken

Medical treatments

Emergency teams may support breathing and circulation, use a heart monitor, give fluids through a drip, and treat pain. Burns are cleaned and dressed, and infection is watched for. Clinicians may give a tetanus vaccination if needed and medicines to treat infection if one develops. People with serious injuries may be cared for by a burns, heart, nerve, or intensive care team.

When is surgery considered?

Surgery may be needed for deep burns, to remove dead tissue, to place a skin graft, to release dangerous pressure in a limb, or to repair injured nerves, blood vessels, or bones. Some scars are treated with surgery later once the wound has healed.

Living with this condition

Healing can take days to months, depending on how deep the injury is. You may feel tired, sore, or anxious for a while. Follow your wound care plan, keep appointments, and ask for help with everyday tasks if you need it. Return to work, school, or sport only when your clinician says it is safe.

Lifestyle tips

• Check your home for damaged cords, old wiring, and cracked sockets
• Use safety switches and have electrical work done by a qualified electrician
• Keep children away from sockets and teach them not to put objects into them
• Never use electrical items with wet hands or near water
• Take extra care during storms and avoid open ground or tall trees when lightning is possible

Diet and exercise

Eat regular, balanced meals and drink enough water to support healing. Gentle movement helps circulation, but avoid using an injured limb for heavy tasks until you are cleared. A physiotherapist can guide safe exercises if you have stiffness or weakness.

Mental health and emotional wellbeing

It is common to feel shaken, worried, or on edge after an electrical injury. Some people have nightmares, flashbacks, or fear of electricity. These feelings can improve with support. If you feel overwhelmed, tell your doctor or nurse. If you feel unsafe or in crisis, contact your local emergency number or a crisis support service right away.

Prevention

Yes. Many electrical burns can be prevented with simple safety habits at home and at work.

Vaccines

There is no vaccine for electrical burns. Keep your tetanus vaccination up to date as advised by your clinician.

Screening programmes

There is no routine screening test for electrical burns. Home and workplace electrical safety checks are the best prevention.

Complications

If left untreated

• Serious heart rhythm problems or cardiac arrest
• Deep muscle, nerve, and blood vessel damage
• Dangerous pressure in a limb, called compartment syndrome
• Kidney injury from muscle breakdown
• Infection of burns
• Scarring, stiffness, and contractures that limit movement
• Fractures or other injuries from a fall or muscle spasm
• Ongoing pain, numbness, or weakness
• Anxiety, nightmares, or distress after the shock

Long-term outlook

Most people with a minor shock and no symptoms recover fully. More serious electrical injuries can take time and specialist care, but early treatment, rehabilitation, and support give the best chance of a good recovery. Many people return to their usual activities.
