Ann & Sara, I had actual clusters as well, I say had, because the in-patient treatment at Chelsea with MHNI helped to break a portion of it. (Knock on formica), gone is the head banging, rolling on the floor, call the ambulance pain, but I still go into significant pain cycles at the winter and summer solstice...which, I know, I'm starting into a cycle as we speak; now I'm classified as "cluster features".
I will average 5 to 7 headaches a day, with the pain increasing as the headaches go on through the day, my ear hurts, eyes start tearing and my nose gets congested (I should say the left side), my pain is left side predominant.
Anyway, I with you with this idea!; I'm curious to hear what people are using for abortives now, my mainstay has been fioricet, but it is starting to lose its efficacy and that has me worried.
