Welcome to HealthcareMagic forum.
I understand you've had a serious head injury
. Was a CT scan
done following the injury?
Most common injury associated with Head injury is a concussion
. Here the symptoms may last for 2-3 months. Nausea is one of those symptoms. You may also have some dizziness
associated with it.
Menstrual disturbances are usually related to stress associated with injury, but it is important that we rule out pregnancy
too, especially if you were involved in unprotected sexual intercourse. If pregnancy is ruled out with a simple pregnancy test, then the symptoms are probably related to the head injury and you need not worry.
Symptoms of head injury are less likely to worsen after couple of weeks of injury; hence I am not really worried of serious head injury. But I do wish to rule out pregnancy before you relax on this issue.
Hope this answers your query.
