As we say in N.C. : "Might could be!"

No catalog of triggers; your personal experience is as validly labeled "trigger" as any others events.

Sorry to hear about your friend. It's not an easy decision and the little fellow was probably worth a few tears. I know my 12 year old cat was when he got sick and had to be put down. The crying didn't trigger a headache for me. The only real way to know if it's a trigger for you is to have another good cry and see what happens. I hope it doesn't. It's not something you can easily do without a good reason and, it's all bad enough being sad without feeling like you're going to be punished for it.

Wishing you peace and pain free years,

I learned recently from a very reliable source that the chemical content of your tears varies massively depending whether you're crying from pain, grief or laughter.

Doesn't help, I know.  Just thought I'd mention it.

Omg - I have found crying to be a trigger as well. So much so that it will cause me to have terrible shadows and trigiminal (sp?) nerve pain when I'm in remission (though even in remission I will have the nerve pain almost every night at the same time - everything but the actual headache). It is terrible for me because I suffer from depression (a lot due to the CH) and I have a hard time trying to keep control of my emotions so that I don't trigger myself... I have gotten a lot better about breathing and talking myself down from an emotional "event". It is also terrible because when I am at a 10 on the scale I cry and scream, which most likely perpetuates the problem. I'm sorry that this is also one of your triggers - but take solace in knowing that being able to control that side of yourself will make you a stronger person all around
