A concussion is a brain injury caused by a hit or force to the head or body that affects how the brain functions. Routine scans (X-ray, CT, MRI) usually appear normal, but symptoms should be taken seriously to reduce the risk of a second impact and support recovery.

Symptoms can include headaches, visual disturbances, dizziness, nausea, difficulty concentrating, feeling 'in a fog', and sensitivity to light or noise. Symptoms may begin immediately or emerge up to 72 hours after an impact, and in some cases can evolve over days or weeks.

Every person and concussion is different. Most people recover within 2–4 weeks. If symptoms last longer than 4 weeks, this may be Post-Concussion Symptoms and you should seek review.

Do not return to any contact activity until symptoms are fully resolved. If you struggle with ongoing symptoms, consult a GP and a clinician experienced in concussion rehabilitation (e.g., a specially trained physiotherapist).

If you have any of the above listed symptoms, seek immediate medical attention by reaching out to your local accident and emergency services.

Otherwise you should contact your GP to arrange an appointment to discuss your concern.
