This is my first visit to this website and message board. With all this information I now know I have cluster headaches. Mine are usually triggered about 4 AM in the morning when the room gets cold. I feel the cold air in my nose and if I don't medicate with aspirin the headache will build. Also, as of the last few years, in summertime if I run air conditioning to cool the room at night, that cold air triggers the pain in my nose then on to a headache. I've had an MRI and cat scan of the head an sinuses and there is nothing unusual revealed. Does anyone else have 'COLD CLIMATE" as a trigger for headaches?
