Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
It is possible for anemia
or spondalities to cause such a headache. You should get a complete blood count
done along with a xray of cervical spine
to identify if there is any spondylitis
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
