Lightning strikes bring many problems to people who end up living. Paralysis, neurological injury, heart problems, sensitivity to sound and light, insomnia and depression to name a few.  

But there is a relatively painless and interesting part of a lightning strike that leaves a distinct mark most emergency room doctors can spot in a second. It's also found in the grass after lightning strikes a golf course.

They are called Lichtenberg figures, or lightning flowers. The electrical pattern was named after the German physicist Georg Lichtenberg who discovered them. 

The rare pattern looks like tree branches, roots or a fern leaf that spread over the skin. In some of these pictures, it looks like a faded henna tattoo.

While the exact process on the body is unknown, several medical journals say it's likely the surge of electricity during a strike bursting capillaries and causing red blood cell leakage to rise to the skin surface in an unusual pattern.

The Lichtenberg figures tend to go away in a few days and are relatively painless.

Doctors say they are crucial to lightning strike diagnosis because they have such very distinct pattern. Many times people are knocked unconscious when struck by lightning and end up in the ER not knowing what happened to them. 

When this pattern is present (among other symptoms), a doctor can quickly tell that someone was hit by lightning.
