Which symptom is NOT typically associated with a concussion?

A concussion is a type of traumatic brain injury that often occurs due to a blow to the head or violent shaking of the head and body. Symptoms are varied and can affect both physical and cognitive functions. Common symptoms associated with a concussion include headache, dizziness, and nausea.

Headaches are one of the most frequently reported symptoms and can range from mild to severe. Dizziness is also common, often described as a feeling of being off-balance or lightheaded, making it a well-recognized symptom following a concussion. Nausea, which can sometimes lead to vomiting, is another symptom that many individuals experience after a concussion.

In contrast, a rash is not a typical symptom associated with concussions. While a rash can suggest a variety of other medical issues, including allergic reactions or infections, it does not result from the mechanisms of concussion. Understanding that concussions are primarily linked to the brain and nervous system helps clarify why rashes are not a symptom of this type of injury.
