What is Head Injury & Concussion?
Head injury ranges from a mild concussion (a brief disturbance of brain function) to severe traumatic brain injury (TBI) with bleeding or swelling. Most concussions resolve in 7-14 days but 10-20% have post-concussion syndrome (headaches, dizziness, brain fog, mood changes) that lasts months. Modern guidelines treat this aggressively with vestibular therapy, vision therapy, and graded exercise — not 'rest until you feel better'.
When a second opinion really helps
- You were told 'just rest' but symptoms are worsening 4+ weeks after the injury.
- Headaches, dizziness, or memory issues persist beyond 2 weeks — needs structured rehab.
- MRI was not done despite ongoing symptoms (rule out chronic subdural).
- You're an athlete or driver and need formal return-to-play / return-to-work clearance.
Red flags — call 108 / 102 immediately
- Worsening headache + vomiting + drowsiness (rising intracranial pressure — call 108)
- Seizure after head injury
- Confusion or amnesia lasting >24 hours
- Weakness, slurred speech, or unequal pupils
Frequently asked questions
80-90% resolve within 7-14 days. If symptoms persist beyond 2 weeks, you have post-concussion syndrome — and you need active rehab, not bed rest.
