Dizziness and balance problems are among the most common symptoms reported after a concussion, often resulting from a disruption in the way the brain processes sensory information. When the brain is jolted inside the skull, it can affect the systems responsible for maintaining equilibrium, including the inner ear and the parts of the brain that coordinate movement. While these symptoms are usually temporary and improve with rest, they require careful monitoring to ensure they do not indicate a more serious underlying issue.

Dizziness is a hallmark sign of a concussion and can manifest as a feeling of lightheadedness, unsteadiness, or a sensation that the room is spinning. According to the NHS, a concussion is a temporary injury to the brain caused by a bump, blow or jolt to the head. This “jolt” can disturb the delicate chemical balance in the brain and interfere with the electrical signals that the brain uses to understand where the body is in space. For many, these balance issues are most noticeable when moving the head quickly or transitioning from sitting to standing.
The Role of the Vestibular System in Balance
The vestibular system, located in the inner ear, is the body’s primary tool for maintaining balance and eye coordination. A concussion can cause a “mismatch” between the signals sent from the inner ear and the signals sent from the eyes to the brain. When these signals do not align, the brain becomes confused, leading to the characteristic dizziness and nausea associated with head trauma.
In some cases, the impact that caused the concussion may also physically affect the inner ear structures. This can lead to specific types of dizziness, such as Benign Paroxysmal Positional Vertigo (BPPV), where small crystals in the inner ear become displaced. Understanding whether the dizziness is coming from the brain or the inner ear is a key part of the clinical assessment performed by UK medical professionals.
Types of Balance Problems After Head Injury
Balance problems following a concussion are not the same for everyone and can range from mild swaying to an inability to walk in a straight line. Clinicians often categorise these issues to better manage the recovery process and provide appropriate safety advice.
| Type of Problem | Description | Typical Triggers |
| Lightheadedness | A feeling of being faint or “spaced out.” | Standing up quickly or dehydration. |
| Vertigo | A false sensation that the environment is spinning. | Turning the head or rolling in bed. |
| Disequilibrium | Feeling unsteady on your feet or off balance. | Walking on uneven ground or in the dark. |
| Motion Sensitivity | Nausea or dizziness caused by movement. | Travelling in a car or scrolling on a screen. |
Managing Dizziness During the Recovery Phase
The primary treatment for post concussion dizziness is physical and cognitive rest, allowing the brain’s internal environment to return to a balanced state. During the first 48 hours, it is essential to avoid activities that could lead to a fall, such as climbing ladders or playing sports. Moving slowly and avoiding sudden head turns can help minimise the severity of dizzy spells as the brain heals.
The National Institute for Health and Care Excellence provides guidelines for the early management of head injuries to ensure symptoms like dizziness are monitored correctly. If dizziness persists beyond the first two weeks, a healthcare professional may recommend specific vestibular rehabilitation exercises. These are gentle movements designed to help the brain and eyes “re-sync” and adapt to the sensory changes caused by the injury.
Safety and Environmental Considerations
When balance is compromised, the risk of sustaining a second head injury through a fall increases significantly. It is important to make the immediate environment as safe as possible by ensuring rooms are well lit and walkways are clear of trip hazards. People experiencing dizziness should also avoid driving or operating machinery until they have been symptom free for a period of time and cleared by a professional.
Alcohol should be strictly avoided during recovery, as it can significantly worsen balance problems and mask more serious symptoms. Hydration is also important, as even mild dehydration can increase feelings of lightheadedness. If dizziness is accompanied by a worsening headache or repeated vomiting, it may indicate that the injury is more severe than a simple concussion.
When Dizziness Becomes an Emergency
While most dizziness after a concussion is managed with rest, certain patterns of instability are considered “red flags.” These symptoms suggest that the brain may be under pressure or that there is a more significant neurological disruption.
If a person becomes so unsteady that they cannot stand or walk at all, or if the dizziness is accompanied by weakness in the arms or legs, immediate medical help is required. Other emergency signs include a sudden loss of consciousness, a seizure, or pupils that are different sizes. These signs indicate that the situation has moved beyond a minor concussion and requires an urgent 999 call.
Conclusion
A concussion frequently causes dizziness and balance problems due to the temporary disruption of sensory processing and the vestibular system. While these symptoms can be disorienting, they usually improve steadily with physical rest and careful management of daily activities. Monitoring the nature of the dizziness and following safety protocols is essential for a full recovery and the prevention of further injury. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Why does the room feel like it’s spinning after I hit my head?
This sensation, known as vertigo, occurs because the brain is receiving conflicting signals from your inner ears and your eyes about your body’s position.
How long does dizziness after a concussion last?
Most people find their balance improves within a few days to two weeks, although for some, it can take slightly longer to resolve completely.
Can I take travel sickness pills for concussion dizziness?
You should not take any medication for dizziness after a head injury unless it has been specifically recommended by a healthcare professional.
Is it normal to feel dizzy when looking at a phone or computer?
Yes, “visual vertigo” is common after a concussion because the brain struggles to process the fast moving information and bright light on a screen.
What should I do if I feel like I’m going to faint?
Sit or lie down immediately in a safe place to prevent a fall, and ensure you are staying well hydrated with water.
Can a neck injury cause dizziness that feels like a concussion?
Yes, “cervicogenic dizziness” can occur if the muscles or joints in the neck are strained during the same impact that caused the concussion.
When is it safe to start exercising again?
You should only return to light exercise once you are no longer feeling dizzy at rest and have followed a graded return to activity protocol.
