New to the site, CH suffer for 14 yrs. now.  Got my first CH when I was 39, now they happen every 2 yrs. just like clock work.  Finally got a Neurologist in 2009 that really understood CHs.  Well on January 6th, I got my cycle started my Verapamil (240mg a day), it has been working great no headaches or the tingling.  Since the 15th, I have had level 7 CH every night after I go to bed.  Last night I had level 8 that lasted from 1000pm to 0500am, this is even after I took 2 5mg Zolmatriptian.  Now today the side of my head hurts, my nose has the tingling feeling and a small pain in the eye socket area.  I believe this is what occurred the last 2 cycles before my cycle went away, it is hard for me to remember what has actually happened from cycle to cycle.  Has anyone else experienced this?  Did your cycle end after this long extended CH?  My days, afternoons and early evenings are pain free.

The basic problem, Cluster, can change duration and intensity over time. This is especially true wit new cases but can occur evern after months/yeas of attacks.

But requires getting back to the doc to adjust dosing and/or the meds being used.

There are even cases where all meds stop working after long periods of effectiveness. Why??? but means the same drill: get backt to the doc and start making changes in your treatment program.

Hi Maz & Bob,
I'm only going on from what I've read, and my own personal experience, but it's obvious their will be different opinions on this! Because after all, we are all different.

The attacks are relatively short 1-3 hours, with a very rapid onset. They tend to occur several times a day, most frequently waking the sufferer in the early hours. There are two types of the condition, episodic and chronic. In the episodic form, the attacks occur in a bout lasting several weeks 4 –12, after which they disappear only to re-appear at some later date. This is where the name cluster headache comes from. Chronic sufferers do not get this relief, and their attacks can continue daily for many years.
