Does a car crash have you seeing spots in the hours or days that follow? Some of the most benign symptoms may point to serious and severe trauma lurking just below the surface. 

Although it may seem contradictory, it is often mild car accidents that result in brain injuries. Out of these, only a fraction of those involved seeks medical attention immediately following the crash. This is usually because no apparent signs or symptoms of head trauma are present. If you have gone through an accident and walked away believing you were healthy, keep an eye out for some of these sneaky signs your brain is in trouble. 

Visual and auditory problems 

When you start to see bright flashes of light or hear a ringing in one or both ears that gets worse, you may want to head to the hospital for testing. The brain is a complex organ that is responsible for every other facet of the body. As such, even a low-impact injury may cause it to malfunction for a time. Because you will not know the extent of the damage until a doctor takes a look, you should go for a diagnosis immediately upon the onset of any strange symptom affecting the senses. 

Excessive sleepiness or insomnia 

When a person who usually has no trouble sleeping suddenly cannot after a crash or develops excessive daytime fatigue, the brain may have a problem. Perhaps you attribute the change in sleep to the stress of dealing with a car insurance claim, but it can signal something far worse. Brain swelling or even a small bleed may become worse if no intervention occurs. Any irregularities with sleep or exhaustion warrant a trip to the doctor. 

The safest thing you can do following a car crash is to seek medical attention. The force of impact in a low-speed collision may impact the brain, causing it injury. The longer you go without help, the higher the risk of long-term damage.
