What are the common symptoms of a concussion?

The common symptoms of a concussion encompass a range of physical, cognitive, and emotional indicators. Headache, confusion, dizziness, nausea, and balance problems are particularly prevalent following a concussion. Headaches often manifest as a pressure or throbbing sensation and can vary in intensity. Confusion can present as difficulty concentrating or feeling "foggy," while dizziness may lead to a sensation of lightheadedness or unsteadiness, impacting balance. Nausea frequently accompanies these symptoms, contributing to overall discomfort and distress, and can sometimes progress to vomiting.
