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.
There is a possibility of tension headache
and the same cannot be diagnosed on any investigation. Basically such pains reduce significantly with amitriptyline
and if that has not been tried then it should defenitely be tried.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
