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.

Full of articles, blogs, book: written by one of the best headache docs in the Chicago area.
Worth exploring. The latest book is in e-book edition, $10; comprehensive and worth buying for
a careful read.
==================
The initial presentation of symptoms can change marekedly for weeks to several months before they settled down, i.e., don't panic with changes but keep the doc informed.
=====
You may expect, from a skilled doc, a three step treatment program.
1. A brief period of a steroid which will kill attacks within a few hours but then tapered off as,
2. A long acting med with blocks/reduces attacks is started but takes a few days to become fully effective.
3. And then, for long tem use, a fast acting abortive med which kills attacks which sneak past #2.
You'll see these meds reviewed in the PDF file.
As painful as Cluster are, there is no danger--permanent disability, etc. Once you get a good treatment program working, the majority of us are able to live quite normal lives.
BUT, immediately: NO alcohol. It's a powerful trigger for an attack. The role of smoking is not clear but tapering down/off is a good idea if she can do it without too much stress.
Assuming it's Cluster, you'll be with us for a long time so keep on reading.
