Unlike many other back/spine/neck injuries it can take a while – often between 8-12 hours – for the extent of whiplash to become clear. It is not uncommon for someone to suffer an impact that causes this injury to feel absolutely fine for several hours afterward, which is why it is important to take immediate precautions right away. It is also worth noting that whiplash tends to get worse over the following week or so.
Sometimes whiplash can result in other symptoms that are very similar to a concussion. Dizziness, short term memory loss, acute sensitivity throughout the limbs, loss of concentration, confusion and mood changes/irritability are all tell-tale signs that someone may have suffered this injury.
