Hi DanAge50,
Welcome to Clusterville, a nickname of this fabulous website where you will have opportunity to educate yourself, share knowledge with those medically treating you for CH's, and be supportive to others.
You've been provided excellent advice from reputable & well respected others thus far...specifically to see a headache specialist; not some nurse practitioner who claims to have had a CH before. Get yourself checked out, properly diagnosed to rule out anything that may be similar to the symptoms of CH's, which may actually be more sinister and harmful such as a tumor. And that Imitrex injections are not limited to those who are unfortunately chronic, and that Imitres pills take too long and not generally advised as effective compared to Imitrex injections and sometimes Imitrex nasal sprays.
You have more information here on this website that any other source - gathered and shared these past 20 years or so since this website creation; and thousands upon thousands of posts to provide educational tools to assist you and your doctors. Keep in mind - we are NOT doctors, just fellow CH'ers who have learned a few things over the years and are always still learning thanks to those willing to share their stories and educational findings.
Many of the best posts are found by searching in the archives from years past, as most of the original members of this site unfortunately do not contribute much, if at all, any longer. However you have already been fortunate to have advice by some of our most respected current members who do post regularly and are very knowledgeable and caring individuals from all walks of life who unfortunately also share this curse. Needless to say, You are NOT alone! We DO understand!
There are no stupid questions! Everything you need to understand about this disease is here on this site. Someone will reply to you at all hours of day or night.
Suggest you begin your education on CH's by reading everything from the yellow tabs on the left side of this webpage. You will no doubt become very pleased to learn more than your doctors, as they come here for their education. This website is the best source of information found anywhere in the world on CH's.
Keep in mind that as Maz pointed out, Imitrex is a tough drug. There are other abortives available to you that are less harmful on your body and wallet. e.g., Hyperventilating 100% oxygen with a non-rebreather mask at 15 to 25 lpm. This can be prescribed or use welder's o2 available without prescription. See the o2 tab and plenty of threads regarding oxygen as abortive. RedBull energy drinks were suggested already...read on this too as a quick abortive option in a pinch.
It is not advised to suffer through a cycle by using only abortives. We suggest you educate yourself and consider some of the Preventative and Transitional treatments, in addition to the Abortive treatments.
Many CH'ers swear by the anti-inflammatory vitamin regimen which is all natural, no prescription required, and inexpensive comparably to traditional medicines of Preventative, Transitional, and Abortive treatments.
Do some reading - ask some questions, feel free to vent your frustrations, get yourself pain free, live between the hits!
Many CH'ers have left this site due to lack of privacy as it is a public forum and easily found via search engines.
Suggest you do not divulge too much personal info to protect your anonymity. Keep in mind as an option that we can help you get to educated medical professionals in your area who are familiar with CH treatment and recommended by others on this site who reside in your area....so if you share where you are located, we can steer you to those recommended doctors.
"Together We Fight!"
Pain Free Wishes
