A lot of people still purely link concussion with headaches. While headaches are a common symptom with concussion, and needs to be taken seriously, not having a headache with concussion is also very common. The absence of a headache does not make the concussion any less serious! Other symptoms such as difficulty concentrating, being 'in a fog' and slowed down can all be debilitating, especially if not addressed correctly.
Here's a list of the most common symptoms after a concussion: Headache Sensitivity to light Sensitivity to noise Pressure in head Feeling ‘slowed down’ Confusion Neck pain Feeling ‘in a fog’ Drowsiness Nausea or vomiting Feeling 'not right’ Trouble falling asleep Dizziness Difficulty concentrating More emotional Blurred vision Difficulty remembering Irritability Balance problems Nervousness/ anxiety Fatigue or low energy Sadness Potentially more!
What is also very important to remember is that, even if the symptoms have resolved, it does not mean you have recovered!
Symptoms going away does not mean the brain neurons have healed - see a concussion specialist to make sure before returning to sport.
