A hospital ER is one of the worst places you could go! Our pages are full is misdiagnoses coming from folks who have no traiing in complex headache disorders. General neourologists fall in the same category.
Compounding the issue of poorly training docs is the reality that there are many disorders wich mimic Cluster but which are not headache disorders.

Best move is to find a headache specialist.
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.

WHY A HEADACHE SPECIALIST IS RECOMMENDED
Headache. 2012 Jan;52(1):99-113.
Cluster headache in the United States of America: demographics, clinical characteristics, triggers, suicidality, and personal burden.

THERE REMAINS A SIGNIFICANT DIAGNOSTIC DELAY FOR CLUSTER HEADACHE PATIENTS ON AVERAGE 5+ YEARS WITH ONLY 21% RECEIVING A CORRECT DIAGNOSIS AT TIME OF INITIAL PRESENTATION.
==========
Now the lack of insurance/$ issue.
Call the social service office of the largest hospital in your area and ask them if they can refer you to a free/low cost clinic/agency. Make sure you want a headache specialist, NOT neurologist.
Sadly, we have many folks here who have wandered around for years before getting the reflief which comes with the correct diagnosis.
You'll receive a variety of ways to treat youself but keep in mind that you still need an accuracte diagnosis both for you personal safety as well and relief.
