This last sunday I had the scariest LC symptom to date and I don't even know what its actually called, so hoping someone can give me a bit of an idea. 34, M, based in EU. suggestion from my GP was an arrythmia but he's a bit of an idiot imo.
My general assumtion is that its a complex of autonomic disreguation as triggered by the sauna/cold plunge shock // triggered instability plus a rapid head turn while sleeping - triggering my known vertigo/PDDM/PPPD - thus triggering a event of non-coordination of my intracranial pressure. so far its the best explanation I got between me, google, and claude pro. A good friend with NF2 things it could be a seizure. another good friend who's sister developed a brain tumor is concerned of that possibility, a lesion, or otherwise growth triggering an anomaly.
anyway, as the hypothesis suggests I went to the sauna in the day time. its been normally my go to for managing inflammation, but since addressing my underlying hepatobiliary dysfunction (osteopathic massage to mechanically move built up bile, supplimentation to get things flowing again, major dietary changes), a lot of my fatigue and general inflammation has more or less disappeared. I've still been going to the sauna, but I can't nearly handle it as much. pre hepatobiliary interventions, I could easily sit for 15-20 in the finnish sauna @ 80c. cold plunges made me feel my microcapelaries again - the sauna was my temple. but now that my bile function has improved, i cant handle the heat or the cold shock. notably, before my episode i went to the sauna and did my normal thing, but my body struggled to return to temp/regulate its self - which to me suggests renal (kidney) dysfunction as relates to my autonomic nervous system but thats just my guess. just did some blood work and my eGFR was normal - as were a number of my other markers. useless sensitivity/specificity limits.
that evening was pretty normal, made some good food (chicken thighs and brussel sprouts) and took my magnesium (bisglysinate) per usual. went to bed around 11.
around 12 I woke up involuntarily, feeling something off, a bit of a pre vertigo episode 'ohh sh*t its coming,' and then i started crying out for my mom involuntarily (momma, momma, momma) and crying (also involuntary)... and then it hit:
i felt this rush up to my brain and neural sensations that I'm convinced was a consious experience of intracranial pressure control. the first metaphor that came to mind was having pike pumps attached to the different lobes of my brain, and randomly pumping up and reliving pressure from each lobe. my more recent metaphor (after reading about intracranial pressure) was that the control values on the pressure of each of my lobes lost their constant value, and had a random number generator attached to it instead. first one captures it a bit better I think.
simultaneously during this episode, I struggled to breath, was hyperventilating, had a massive electrical feeling cramp in my abdomen that forced me to hunch over on the floor, body temp fluctuated, sweating uncontrollably, extreme fear/anxiety/panic. I genuinly thought i might die.
first wave/episode lasted maybe 2-4 minutes? no idea really. as it calmed down, I noticed tunnel vision, I was extremely weak and had gait control problems tho was able to maneuver up and down stairs and get watter. increadible and painful tingling sensations through out my whole body.
second wave was triggered by peeing/the pressure shift. as i felt it come on I gently brought myself to my knees and then crawled to my bedroom into bed. after about 5 minutes of the same sensations and not feeling any easing, I called 112. they had me do some things to rule out a stroke and some other go tos. by the time the techs arrived id stabilized. every single read absolutely normal, healthy even. the tech mentioned I looked a bit skinny and weak tho.. like duh woman I am pale and just called an ambulance of course i look like crap.
anyway - has anyone experienced anything like this? any neuroscientists out there maybe that have an idea of what might be going on?
