Having a diagnosis is very important because it excludes other conditions (Tumors, anatomic variations and treatable causes) and saves you from wasting time with treatments that have been proven not to work (oral imitrex, botox, surgery, most medications). You can also concentrate your self education efforts with a laser focus. Do not expect the medical establishment to take charge and treat you. You must direct your own treatment within boundaries you set. Cluster headaches are a diagnosis of exclusion which means after ruling out other potential causes all you are left with is cluster headaches. The criteria are pretty straight forward but overlap some other conditions. Many headache conditions respond to imitrex, very few respond to O2 therapy used properly. i am going to try and attach an article from "Up to Date" which is an online "go to" reference for many physicians and mid level providers. It is a peer reviewed, frequently updated, referenced resource designed to help experts and non experts stay abreast of treatment guidelines for many conditions. The attachment are treatment guidelines for cluster headaches and you might consider printing it off and bringing it to a provider or ER visit as you seek a partner to manage cluster headaches. The attachment is a bit large and may not be allowed to be updated. Maybe an administrator can help if it doesn't upload. You can PM me if you want and I'll email it if you wish. @CSA get a diagnosis.
