What is a common symptom of a concussion?

A concussion is a type of traumatic brain injury that can result from a blow to the head or a jolt to the body that causes the head and brain to move rapidly back and forth. The symptoms of a concussion can vary from person to person and may manifest immediately or develop over time.

Nausea, headache, and dizziness are all recognized symptoms of a concussion. Nausea occurs as the brain undergoes trauma and imbalance, often leading to feelings of sickness. A headache is one of the most common symptoms and can result from the brain's reaction to injury. Dizziness, or a sensation of spinning or imbalance, can also occur because of the disruption in normal brain functions.

Since all three symptoms can commonly appear as part of the response to a concussion, the best answer encapsulating these possible symptoms is that all of the mentioned options are common symptoms of a concussion.
