Hello,
Thank you for asking at HCM.
I carefully read your question and understand your concern.
if your husband fell from the bed and the height is less than 1.5 m it is very unlikely he has serious
head trauma. If he did not loose the consciousness after the trauma and has no
vomiting, this is reassuring also.
As you explain he does not have neurologic signs and cognition is good so the headache can be caused by the local trauma of the structures and not necessarily due to serious causes.
You seem to be doing the right things with local ice,
tylenol for pain.
You can also give him some
advil if tylenol does not help enough.
Make sure he takes advil after food so it does not hurt his stomach.
If pain does not get better with the above measures or if he gets any worse or develops new symptoms you need to urgently see a doctor and have an evaluation and proper treatment plan.
Hope this is helpful and answers to your question
