Hello
I've had the Cluster headaches since around 2016 , then l was not aware of what they were or why.
It always affects the right side of my head when the attacks happen .
After l was diagnose from my Neurologist , he issued Verapamil at 80 milligrams six times per day.
I found taking that many pills was hard on my system , to many side effects.
So l was cutting back on Verapamil to find the right mix of pills.
My cycles were always later September when they started and end around the first week of February.
I would only take the Verapamil when the season started then around late March, and that seem to work for a few years.
I would have headaches around late evening always the same time every day.
He also issued Sumatriptan 100 mgs and Rizatriptan at 10 mgs as well to stop the pain when they peaked 10/10.
When the headache ended l would fall asleep fast when taking triptan cocktails of pills but they worked.
So for the first 5 or 6 years or so they were like clock work they start up again late fall and then early February
Then one year l hardly had any at all. Didn't know why either.
My neurologist gave me a prescription for the shot in the back of my neck had it twice , but it did not work.
A couple of years back l got on oxygen and l found that it really helps , it stops them before they build, hence no more sumatriptan or Rizatriptan to kill the pain .
I still get shadows at times that linger , but now I take Verapamil 80mgs three times a day and that keeps away for good.
I don`t get off the Verapamil at all now.
I live in the western part of Canada I am a senior now ,and also male, but when they started I was in my late fifties.
We travel a lot and I find that the atmospheric pressure has a lot do with headaches as well.
I hope this helps as you are not alone with this condition.
