Hi,
I am Dr Mbong. After a
head trauma, one may sustain an internal
head injury (such as a bleed of sub-dural origin) which may get bigger slowly overtime and cause symptoms months after.
So though it is 4 months after what you had, it is advisable to urgently see a physician for examination and a
CT scan among other investigations to make sure that the symptoms you described are not related to the head trauma you had.
Quick recovery,
Dr Mbong
