What is the worst thing that will happen if you go to doctor for a concussion?

The worst thing that can happen if you go to the doctor for a concussion is that you will unnecessarily undergo costly medical tests and be prescribed unnecessary medication. In most cases, concussions are mild and will resolve on their own within a few weeks. Medical intervention is typically only necessary for more severe concussions that are accompanied by loss of consciousness, vomiting, or other concerning symptoms. If you are experiencing any of these symptoms, it is important to seek medical attention. Otherwise, you may be able to manage your concussion at home with rest, pain relievers, and ice.
