mine started at about 17 years old, kept coming and going as they do, getting more and more intense each cluster, at about 45 years of age i was prescribed imigran injections brilliant back to work in 3 minutes. Problem was i got used to them and was in my most prolific cluster, on the worst day i injected 18 times, after that my attacks abated gradually over a few weeks , apart from mild "I'm still here" individual pains lasting seconds, I've been free since , I'm now 54 years old.
I hope you and all sufferers get your cures.
P.S my Dad suffered until the age of 50
