LOCATING HEADACHE SPECIALIST

1. Search the OUCH site (button on left) for a list of recommended M.D.s.

2. 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.

3.  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.

4. Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to or  On-line screen to find a physician.

5. Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to or Look for "Physician Finder" search box.  Call 1-800-643-5552; 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.
