I've suffered from CH for 15 years now. The attacks would always be on the right side. My clusters would occur once a year, in 2-3 week clusters, and I would have about 1-2 attacks daily.
This year, my cluster is lasting an unusually long time. It started about 5 weeks ago, on my left side only as usual. However 2 weeks ago I got my first ever attack on my right side. This really freaked, me out because it never happened before. Now for the past 2 weeks I've been getting attacks only on my right sidea.
Has this ever happened to anyone else?
