Do I have to lose consciousness to be concussed?
No, and most people do not. Feeling dazed, foggy or "not right" after a knock is enough.
Should I rest completely in a dark room?
No — that advice has changed. Two days of relative rest, then gradual increase in activity. Prolonged complete rest is associated with slower recovery.
Does a normal CT scan mean I am fine?
It means there is no bleed, which is the important thing it is looking for. Concussion does not show on a CT, so a normal scan does not mean you are not concussed.
When can I go back to sport?
UK grassroots guidance is at least 14 days symptom-free before contact training, and a minimum of 21 days from injury before competition — longer for children. It is stricter than most people expect, and the reason is second impact syndrome.
How long will I feel like this?
Most adults recover within two weeks and most children within four. A minority have symptoms for longer, which is recognised and treatable — not imagined.
Can I take ibuprofen?
Use paracetamol in the first 24 to 48 hours and avoid ibuprofen and aspirin, because of bleeding risk. After that ibuprofen is usually fine.
Can I drive?
Not until symptoms have settled. Concentration, reaction time and vision are all affected, often more than you realise.
