I doubt it's a coincidence. Any nrelieved stressor can kick off a CH or a migraine or a tension headache. It sounds to me as if you would profit from examining the various stress points in your life and reevaluate how you deal with them. Just my thoughts. Blessings. lance

I've been experiencing the same thing.  On the downhill side of a cycle right now and I'm getting lots of non-CH headaches which is odd for me since when I'm not in cycle, I rarely have headaches.

I chalked it up to all the additional stress that the beast causes, but sounds like there might be a connection...

I was just diagnosed with CH and for the entire month before, thought I was having non-stop migraines that would just peak in brutal intensity.  Neurologist helped me distinguish between the Cluster Headaches, and the rest of the time, during the cycle, I had tension headaches.  I believe as a result of the stress and pain of dealing with CH everyday.  I think my cycle ended, and about 5 days after the last CH, my tension headaches finally subsided as well...
I really wouldn't be surprised if you had TH as a result of the anxiety and stress surrounding the non-stop cluster headaches.
