My cluster headaches started just before my 18th birthday. I wasn't properly diagnosed til 1996. That's 16 years of dealing with cluster headaches not knowing what they were. My cycles last any where from 8 to 40 weeks with the majority of cycles lasting 8 to 10 weeks. I usually had 2 sometimes 3 cycles a year and my trigger for the start of a cycle was the change of season. Over the last 10 years my cycles generally happen once every 3-4 years lasting 4-5 weeks.
Oxygen and Verapamil work best for me. With the support of the wife, sons and the cluster head family, I am still here and learning new things about our disease. Keep your chin up and ask allot of questions, the veterans are willing to help. There are a number of different groups on Facebook that have 1000's of members, so the help is out there you just need to ask. PFDAN (pain free days and nights) to all.
