A person who was affected by a nearby<unk>  strike. Note the slight branching redness traveling up the victim's leg from the effects of the current. Common<unk> es caused by<unk>  include: muscle pains, broken bones, cardiac arrest, confusion, hearing loss, seizures, burns, behavioral changes, and ocular cataracts. Loss of consciousness is very common immediately after a strike.<unk>  burns result from energy caused by<unk>  strikes, and are characterized by a unique pattern of skin lesions. These tree-like lesions resemble feathering or ferning, and are also called Lichtenberg figures. The marks are formed when capillaries beneath the skin rupture due to the electrical discharge and they usually appear "within hours" of the strike though they tend to disappear within a few days. They also generally occur on the upper body. The brief duration of the exposure frequently limits the damage to the outer layer of skin. The intense heat generated by a<unk>  strike can burn tissue, and cause lung damage, and the chest can be damaged by the mechanical force of rapidly expanding heated air. Just as heat can cause expanding air in the lungs, the explosive shock wave created by<unk>  (the cause of thunder) can cause concussive and hearing damage at extremely close range. Other physical<unk>  can be caused by objects damaged or thrown by the<unk>  strike. For example,<unk>  striking a nearby tree may vaporize sap, and the steam explosion often causes bark and wood fragments to be explosively ejected.<unk>  strikes can also induce a transient paralysis known as 'keraunoparalysis'. Signs and symptoms of keraunoparalysis include lack of pulse, pallor or cyanosis, and motor and sensory loss in the extremities. However, keraunoparalysis usually resolves within a few hours.
