Wow, this is crazy that other have these same episodes.
High BP, extreme cold, and shaking.
Mine usually start out with a prodrome of temperature dysregulation - usually cold hands, and sometimes sweaty. Then I get a sudden surge of extreme fatigue and tiredness and it feels like I’ll pass out unless I lay down. Then my body rebounds and BP surges. I feel like there’s little blood in my head and my vision starts smearing and looking terrifying. I get super confused. I shake and shiver like I’m seizing almost.
Highest I recorded my BP is 160/100. Usually resolves in an hour or so. Have visited ER but symptoms calm down by the time they see me and I’m told it’s just panic - I’ve experienced panic attacks too and these are wildly different.
One thing that sound similar is paroxysmal sympathetic hyperactivation. Seems this could be related to sympathetic trunk issues from instability, irritation, or some other cause of dysautonomia.
I’ve found that these episodes are lessened when I’m taking zinc, vitamin C, or resveratrol the same day. Oddly I have had them occur on gabapentin which helps other symptoms. Ativan does usually calm them down but not every symptom. But sometimes seem caused by benzo rebound.
They also sometimes seem triggered by allergies. Ruled out heart arrythmia.
I’m not convinced they’re 100% related to ES for me but would like to hear more details from your experiences.
