My father-in-law has been diagnosed with ch. He has had them for 17 years. When I asked him how often they occur he said that the longest break he has ever had between clusters is 4 months. He said they usually occur every 2-3 months and last for up to 6 weeks. He said he's had one headache last three days. Anyway, you have all been really helpful and I thought maybe you could tell me why he seems to have them so often compared to others with ch. Please email me at st911@hotmail.com if you have any ideas. Thanks!
