Hello and welcome,
Thanks for your query.
Normally, after a head injury
we prefer scheduling a CT scan of the head to rule out all possibilities of any damage internally. But at times we also wait till we observe any symptoms (neuro ictus) like loss of consciousness
(LOC), nausea, vomiting
, sever headaches
, hearing loss
, seizures, etc.
The blood shot eyes of your child could also be because of lack of sleep, as you said he stayed up till late. But it could always be best to rule out the worst instead of sitting in the dark with it.
I advise you to get a scan of his head at the earliest.
Wishing you and your family the best. You can write back to us anytime for further inquiries.
