Hello. Thanks for asking from HCM.
I can understand your concern. It is good that his investigations are normal.
Head injury can cause headache which increases due to noisy sound, bright light,
stress. It may be the reason behind his irritable behaviour as his headache increases and he becomes uncomfortable.
Another reason could be "Concussion". It is a type of blunt head injury followed by
unconsciousness and memory deficit for incidence without any evidence of bleed or damage to brain. It can cause headache, memory deficit, irritability, confusion for few days. Recovery is the rule. Symptoms usually subside in 10 to 14 days.
For relief, you can follow few tips
: Avoid pressure at injury site
: Keep his head at higher level than chest
: You can take painkiller like
Diclofenac sodium after proper prescription
: Avoid noisy sound, bright light, physical and mental stress
: Still no relief or his symptoms increase, you should
consult doctor. Repeat scan may be advised to rule out delayed bleed or oedema. Further treatment will be decided after report.
Hope it will help you.
Thanks. Take care.
