Kitty,

You may need to find a headache specialist. They're often neuros, but some have come from other specialties as well. Basically, they're doctors who limit their practice soley to headaches (and sometimes one particular type of headache, like migraine).

While you're looking for one, start keeping a headache log/journal (Google: headache log for examples). This will help you (and the doctor) identify the type and cause of the headaches (if one can be found).

If triptans once helped, migraine and/or cluster headaches are a possibility. You can also Google: headache diagnosis, headache identification, identifying headache type.... things like that may lead you to some clues as well. The better informed/prepared you are when you find a specialist, the sooner s/he should be able to help you.
