When Do Concussion Symptoms Start? 


It is common for people to experience concussion symptoms just hours after injury, but the majority of concussions are not diagnosed until days later. Concussion symptoms may include headache, fatigue, dizziness, and nausea. These symptoms typically start within a few minutes or hours following an impact to the head that causes trauma or if there was a loss of consciousness.


What Are The Common Causes Of A Concussion?


A concussion is a type of traumatic brain injury that results from the head being hit with enough force to cause damage. People who play contact sports like football and soccer are more likely than others to sustain concussions, but anyone can get one after falling or getting into an accident where they bump their heads against something hard. Most people recover completely within weeks of sustaining a concussion; however, it may take months for some symptoms – such as headache pain or dizziness – to disappear entirely.

  • Be aware of the danger of concussions
  • Learn what to do if you have one
  • Know how long it takes for symptoms to disappear after a concussion


What Are The Symptoms Of A Concussion?


A concussion may not be immediately obvious, and the symptoms might continue for days or even months. Among the signs and symptoms are:

  • a headache that won’t go away or that isn’t eased by pain relievers
  • dizziness
  • feeling nauseous
  • memory loss
  • strange behavior – you may not remember what occurred before or after the injury
  • clumsiness or balance problems
  • agitation or rapid mood swings
  • changes in eyesight, such as blurred vision, double vision, or “seeing stars”
  • you may be knocked out or find it difficult to remain awake

Common symptoms in children include:

  • a lack of interest in people or objects
  • a lot of crying
  • changes in their eating or sleeping patterns


How Will I Recover From A Concussion?


No matter when your symptoms present themselves, you should start recovering as soon as they appear. Avoid strenuous activities for the first 24 to 48 hours like sports or other physical activities that might jostle your head until you check with the doctor.

During your brain’s resting period, avoid stimulating yourself with tablets and phones. If you can’t do without them on the bedside table, try to reduce their use as much as possible by keeping them out of sight or even turning off notifications for a few hours if they usually stay within arm’s reach at all times during sleep time. Remember that physical activity like driving or exercise is also not recommended because it will interfere too much with your natural ability to fall asleep quickly in this short amount of time.

  • Keep your brain rested with less screen time
  • Get better sleep without the use of medications
  • Improve mood, energy, and focus when you wake up

Following a 48-hour period, you should be able to gradually resume your normal routine. However, avoid sports and extracurricular activities for the time being; instead, focus on walking around.

If you have a severe concussion, symptoms may take up to 14 days for complete recovery. If it’s more than 10 days after the initial injury and your doctor recommends that you go through a comprehensive concussion recovery program at an inpatient facility, this means that there is likely further damage from the brain trauma which needs time to fully recover.

  • If you’re not fully recovered after 10 days, it may be time to start thinking about a recovery program
  • Get back to your life in the quickest possible time
  • Equips patients with the correct treatment for their concussion

Headaches, nausea, dizziness, difficulty remembering, and fogginess are all symptoms of a concussion. Although the severity of these symptoms can vary from person to person it’s important to call your doctor if you experience any at all.
