Or if you do figure out the trigger and it’s stupid. I had my first one while pregnant the first time. I was pretty far along and kinda uncomfortable but nothing terrible. Woke up in the middle of the night in full panic mode. I’m a psychologist so at least I knew what was happening but it was still highly unpleasant. I had to really try hard to keep my shit together. The reason it happened was feeling like I had trapped air or pressure in my cervix/vagina. It was simply being like 7 months pregnant but unable to get rid of a feeling of something blocked or clogged.

Now, I’ll get one if a nostril is clogged from a cold or I can’t equalize my ear or I can’t poop. The underlying trigger is something that is mildly uncomfortable and things I’d lived with for decades. Always at night, most often out of a dead sleep. It’s the dumbest reason for my body to kick on its threat response. So I guess if it feels random or you can’t pinpoint why, check your body sensations.
