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.

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

4. Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to or 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.

5. Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to or 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.

And this last reference should make it clear that this is not a do it youself condition when it comes to both diasgnosis and treatment.

Bob, I am not leaving diagnosis to you, me, or anyone else on this forum. I will be seeing a trained physician next week to take care of other issues, sugar, high bp etc....i will initially address it with him since I will be there, and then go to someone with CH experience..at this point, the current attack is about done. I am pretty confident the headaches will be gone by the time I see him. Like I said, whatever this is, it is like clockwork.

That's a great post Sean !
Hey Kevin,    One thing with this horrible disease, is that there are many similar mimicking ones, very much like it !
Some, not very pretty !
This is probably why guys like Bob, who has a wealth of support information to offer, pushes the need for proper diagnosis. Generally, a suitable headache specialist will run a cat scan or MRI, to eliminate the possibilty of brain tumors ! Yep, near soiled me nappies when I was given the reason why I was having one !  But, that's the realities we must face, its not a good feeling waiting for results, But an elimination process we all must go through.  Getting a Proper headache specialist is a real must, a lot of us on here have gone through the mill with even neurologists fumbling there way through treating us, with no real experience in the condition, So shoot for the best you can find, Bob often asks where are you from and can give you a list of all the recommended ones that have experience in this disease.
At the end of the day, Sean is right, once diagnosed, sufferers do really become the experts !  There's a hell of a lot of them on here, in all shapes and sizes.
If it does end up being diagnosed as cluster headaches, then you've come to the right place.
