Can you get a fever from concussion?

A concussion is a traumatic brain injury that can occur when a person's head is struck hard. Symptoms of a concussion can include headache, dizziness, nausea, vomiting, confusion, and memory loss. In some cases, a person with a concussion may also experience a fever. However, a fever is not a typical symptom of a concussion and is more likely to indicate an infection. If you have a fever after a head injury, it is important to see a doctor to rule out any other possible causes.
