CLuster headaches are caused by dilation of the blood vessels...from what I understand, swelling is something that is often seen with them. It took a long time for me to be diagnosed because they aren't common for the most part and they aren't common at all in women. They aren't like a regular migraine...think of them as a migraine on steroids. When I was a kid I would lay screaming and bang my head against the wall...my parents thought I was throwing temper tantrums
They would take me to the doctor and it would be dismissed as a reaction to some chemical or trying to get attention. I was finally diagnosed when I was in the military.
They tested me for triggers...caffeine, chocolate, cheese, msg, etc. Artificial sweetners are a definite trigger, I haven't found one yet that wont trigger a cluster migraine within 15 minutes...including Splenda. I avoid these at all cost. I read the labels on everything I buy because they will sneak asparteme and splenda into a lot of things. If I drink too much tea I run the risk of it due to the tannins, or too much citrus. I can drink 1 glass of ice tea or 1 glass of lemonade/ orange juice... 2 and I'm taking chances. Those are it that could be found. The rest of the time it is anybody's guess.
I've only been given epinephrine via IV. I think they also give it to me to calm me down when the caffergot doesnt work...the pain is so intense it sends my blood pressure sky-rocketing.
