Muscle pain after electric shock is due to violent muscle contraction during electric shock.
Electricity stimulates the muscle, this is why when an electric current passes through the body it causes the muscle within the pathway of its flow to contract violently. The extent of the contraction is directly proportional to the intensity of the current and the type of muscle it travels through.
Here is what causes muscle pain after an electric shock
When a current above 10mA travels through flexor muscles, such as the ones in our forearms that close the fingers, it causes a sustained contraction; at this point, the victim may be unable to let go of the source of the current, making the duration of the contact longer and increasing the severity of the shock.
Also;
When a current above 10mA travels through extensor muscles, it causes a violent spasm. If the muscles affected are the hip extensors that lengthen the limbs away from the body, the victim may be propelled, sometimes many meters away!
Muscles, ligaments, and tendons may tear as a result of the sudden contraction caused by an electric shock.
This violent contraction of the muscles during electric shock is the reason behind muscle pain after electric shock.
