The fundamental approach to protect against electric shock is to prevent contact with voltages that can cause a hazardous current through the body. Voltages above 30 Vrms or 42.2 volts peak or 60VDC are considered great enough to potentially cause a lethal electric shock to humans.

The same article states that high-voltage currents of 500 V and more can cause deep burns, while low-voltage currents consisting of 110–120 V can result in muscle spasms. A person can get an electrical shock through contact with an electrical current from a small household appliance, wall outlet, or extension cord.

Even without visible burns, electric shock survivors may face long-term muscular pain and discomfort, fatigue, headache, problems with peripheral nerve conduction and sensation, inadequate balance and coordination, and other additional symptoms.

If your sensory nerves are damaged, you may have a feeling of “pins and needles” or “electric shocks.” You may also feel cold, prickling, pinching, or burning in your hands and feet. Some people become very sensitive to touch, while other people feel numbness.

Most of the time, carpal tunnel syndrome gets cured and doesn’t come back. If you have a severe case, surgery can help, but your symptoms may not go away completely.

For many people, the first symptom of a boiling water burn is sudden, sharp pain. However, third-degree burns, or full-thickness burns, damage the nerves under the skin and might not hurt at all.

The signs of nerve damage

• Numbness or tingling in the hands and feet.
• Feeling like you’re wearing a tight glove or sock.
• Muscle weakness, especially in your arms or legs.
• Regularly dropping objects that you’re holding.
• Sharp pains in your hands, arms, legs, or feet.
• A buzzing sensation that feels like a mild electrical shock.

Vitamin B1 (thiamine) provides your nerves with energy to function, while vitamin B6 relieves nerve pain and transmits nerve impulses correctly. Vitamin B12 regenerates the nerves, protecting them from damage. A deficiency in vitamins B12 or B1 may be partly responsible for your nerve pain.

The main medicines recommended for neuropathic pain include:

• amitriptyline – also used for treatment of headaches and depression.
• duloxetine – also used for treatment of bladder problems and depression.
• pregabalin and gabapentin – also used to treat epilepsy, headaches or anxiety.

Fish oil is useful in treating neuropathy due to its anti-inflammatory effects and its ability to repair damaged nerves….The omega-3 fatty acids found in fish oil are also found in these foods:

• salmon.
• walnuts.
• sardines.
• canola oil.
• chia seeds.
• flaxseeds.
• mackerel.
• cod liver oil.
