Thank you for posting your query.
is one of the commonest causes of headache. The location is at back of head (as in your case), it tends to get worse in the evenings. There is no nausea
of the affected area may be useful.
However, in your case, as you have suggested, other causes should also be considered. Migraine
is one of these possibilities.
If the medical treatment does not make you better, you should possibly get a brain scan done to exclude internal problems.
Wishing you good health,
