2. Brain Injury
Brain injury is one of the other most common causes behind optic nerve swelling, and it usually also goes together with a concussion. If you have experienced any kind of recent brain injury, get yourself right to the emergency room – the injury might be considerably worse than you realized at first, and waiting to get to medical help can only put your health in very serious danger. Brain injuries can happen in a variety of ways, and what you might have only thought of as a slight knock might have caused more internal injury than at first thought.
A medical professional can establish the extent of the brain injury, and recommend the right tests and treatment to treat the cause and reduce the potential of any damage. Memory loss and confusion are commonly associated with symptoms, and a brain injury is likely to trigger temporary papilledema. A change in the response of the pupils can also usually be observed in moderate to severe brain injuries.
