how do i know if i have a concussion

To know if you have a concussion, watch for a range of symptoms that can appear immediately or sometimes hours to days after a head injury. Common signs include headache, confusion or feeling "in a fog," memory loss or amnesia about the event, dizziness, nausea or vomiting, ringing in the ears, blurry vision, fatigue, and sensitivity to light or noise. You may also experience irritability, trouble concentrating, changes in personality, and sleep disturbances. Sometimes, symptoms like temporary loss of consciousness, slurred speech, or a dazed appearance can be observed by others. More severe signs that require immediate medical attention include worsening headaches, repeated vomiting, weakness or numbness, slurred speech, difficulty staying awake or being awakened, one pupil larger than the other, seizures, and unusual behavior or confusion. Concussions do not always involve loss of consciousness, and symptoms may vary widely between individuals. If a concussion is suspected, it is important to rest and seek medical evaluation to confirm the diagnosis and manage symptoms safely.
