Hi Serene,
Welcome to healthcare magic!
Such head injuries are mostly without consequences. But symptoms which are still persisting makes it mandatory to rule out any serious internal
injury to brain eg
Subdural hematoma, extradural hematoma, any skull
bone fracture etc which can take place rarely.
You need a physical and neurological examination by your physician and get base line investigations like Chest
X Ray, Electrocardiogram, Complete Blood Counts, Renal Function Test,
Liver Function Test and if really needed then a CT Brain.
This work up is expected to detect the underlying problem so a definite treatment could be started.
I hope this advise would be helpful for you.
Still if you have any queries or doubts, please write me back,
I would be happy to solve them.
Wish you a great health!
