Some burns can look like Lichtenberg figures, or lines. Lichtenberg lines are long, intricate, wavy burns that can appear on someone temporarily after receiving a massive electric shock.”They don’t really stick around. They’re these fernlike, superficial burns of the skin,” said Claypool.
There could be long-lasting effects on the brain as well, including potential memory loss, seizures or muscle spasms.
“There’s really nothing unique, long term, from lightning. You can have these things from any kind of brain injury,” said Claypool.
In Claypool’s hospital, he said they see victims or injuries from lightning strikes every few years. The most common places people were hit by lightning strikes were out on the golf course or sailing enthusiasts out on the water.NOAA has reported three lightning deaths so far in 2017 and 307 fatalities for the last 10 years.
To prevent being struck by lightning, people should seek shelter in an enclosed space immediately at the first sign of a thunderstorm. Inside is best, but cars are the next safest option. Standing under trees or tall pavilions is not considered safe.
