My immediate reaction was: hope you are seeing a headache specialist rather than a geneal neurologist.
Two reasons: 1. gen neu. have meager training/experience witwh complex headache disorders although we assume they are the folks to see. So, encourage a few direct questions with the doc to ask about his educaton/experience, especially with Cluster.
2. This comment reinforced by the possible onset of Cluster at your age. Usual onset is from late teens. At your age it's especially important to have a doc who appreciates that there are many disorders which MIMIC Cluster, but which are not headache disorders.
If any concern about this doc's background consider the following:
LOCATING HEADACHE SPECIALIST
1. Yellow Pages phone book: look for "Headache Clinics" in the M.D. section and look under "neurologist" where some docs will list speciality areas of practice.
2. Call your hospital/medical center. They often have an office to assist in finding a physician. You may have to ask for the social worker/patient advocate.

Look for "Physician Finder" search box. They will send a list of M.D.s for your state.I suggest using this source for several reasons: first, we have read several messages from people who, even seeing neurologists, are unhappy with the quality of care and ATTITUDES they have encountered; second, the clinical director of the Jefferson (Philadelphia) Headache Clinic said, in late 1999, that upwards of 40%+ of U.S. doctors have poor training in treating headache and/or hold attitudes about headache ("hysterical female disorder") which block them from sympathetic and effective work with the patient; third, it's necessary to find a doctor who has experience, skill, and a set of attitudes which give hope of success. This is the best method I know of to find such a physician.

NEW certification program for "Headache Medicine" by the United Council for Neurologic Subspecialties, an independent, non-profit, professional medical organization.
Since this is a new program, the initial listing is limited and so it should be checked each time you have an interest in locating a headache doctor.

While these cautions may concern you, a third consideration is that the rate of Cluster in women is so very low that we still have too many docs who simply don't understand the potential and even deny the possibility of Cluster in women! So, careful screening of your choice is important.
