I have CH and get the nausea of a migraine sufferer. I diagnosed my sister years ago who suffers from migraines, and who has since sought medical treatment.  I have CH, but I do get nauseated. That's  one way i sometimes get relief from the headaches, at times. Each attack is unique and i use various methods to get relief.

I've experienced nausea before from a cluster attack, usually the more intense the pain the worse the nausea. However, I've had plenty of attacks where I wasn't nauseous. Strange things, these clusters are

I have been episodic for the last 11 years.  I have vomited (2) times.  One of them was  last week.  IT happened during the worst attack I have had during this cycle.  (yet)

The one thing I do want to ask about is this- last night was the first time in hundreds, maybe thousands of episodes that I got nauseated.  Why did this happen?  I am not an up-chucker, haven't thrown up in probably 20 years, but last night I sat hunched over the toilet dry heaving until my guts hurt.  I know this isn't normal, and especially for me.  Any ideas?

and Maz.

I'm feeling like the above now, not related to CH but to
much vino.

Hoppy.
