Which of the following is a common symptom of a concussion?

A common symptom of a concussion is a headache. This occurs due to the trauma to the head, which can disrupt normal brain function and lead to pain sensations. Headaches can vary in intensity and duration, sometimes persisting for several days or weeks following the injury. They are often described as tension-like, migraine-like, or similar to what individuals might experience with other forms of head trauma.

While nausea is also a symptom that can be associated with concussions, the question may be specifically targeting the most recognizable and commonly reported symptom, which tends to be headaches in both clinical settings and among patients. Other options, like back pain and chest tightness, are not typically linked to concussions, as they pertain more to injuries or issues affecting the spine or respiratory system, rather than brain injury.
