Hello Sylvi Rah,
Thanks for posting on HCM,
When it comes to head injury
one could never be too sure of the presence of concussion
or not especially when they are no focal neurological which can point us towards the gravity of a head trauma
. Headache could be as a result of a mild head injury (with the inflammation and cut being responsible for it) while it will also be recommended that headache due to increased intracranial pressure be ruled out with a CT scan
as soon as possible.
Based on your description, we can not tell directly if the concussion is mild and evolving to severity or not. Just advise your boyfriend to go to the ER for a emergency care and book an appointment with a doctor.
Hope this helps
