A new onset neck pain
& headache, persisting / increasing over last 3 weeks should be evaluated on priority. you did not mention if your father is having high blood pressure
or not. Most of the time headache is not associated with high blood pressure unless it is very high or patient had bleeding in his head. Still best way out is to consult your internal medicine expert / neurologist
and identify the root cause for pain. a single episode of agitated behavior can be because of multiple reasons and we must not attempt to find out a reason in isolation.
will again recommend an examination on priority basis.
please revert back, if there is any query pertaining to high blood pressure or heart disease
thanks for writing to healthcaremagic.
