How to find out if I have a concussion?

There are many symptoms of a concussion, which can happen after either hitting the head or having a “whiplash” injury where the head moves quickly backward and forward. They include headache, nausea/vomiting, dizziness, difficulty with balance, blurry vision, ringing in the ears, memory problems, fatigue and other neurological symptoms. If you are having any of these symptoms after an injury you should call your doctor.
