Hi,
How are you? Are there other symptoms present? There are many possible cause for headaches. And to identify the underlying cause, diagnostic tests, more importantly, imaging studies as mentioned above can help rule out any anatomical issues. A headache journal may also help identify triggers of the headache even if your headache often wakes you up. Take care and do keep us posted.
you should have an MRI or ct scan done to determine
if there is nothing alarming going on in the brain whether the HA returns or not
just to be sure.
Migraines can vary immensely from person to person.
some people have them everyday, some have them once or twice a year.
but to be sure if you have "just migraine" or other type or "just headache",
you need to exclude other possibilities by doing these tests.
