The incidence of myocarditis and pericarditis in unvaccinated Covid patients

A tag-along tangent to that: I'm curious as to the cases where there are adverse reactions to the vaccine, what is the probability/possibility that the individual's response would be comparable if exposed to the virus directly.

My sister recommended Wim Hoff. I'll scope it out. I had been considering buying an o2 concentrator since 2020 and I do have some voice/breath training and have found some exercises related to that that aren't dissimilar from Wim Hoff show some reduction in symptoms.

Honestly, I feel very lucky to be as functional as I am. I do worry about how medical and political systems are responding to COVID and long COVID, but largely I think good care is going to come from the bottom up and not top down. I'm comfortable(ish) with a reality that I might just suddenly drop dead tomorrow, but this experience has given me a new appreciation for the health I have that I could not have fathomed before. Because I can alleviate symptoms with diet and directed exercise and it does appear to have a cumulative effect on their reduction, I think recovery is possible without intense intervention. I don't even mind being more spacey and a bit dumber. It suits me a bit and has changed the pace of my life in a way that once I embraced has been good.

My biggest worry is that if I suddenly die and how devastating that would be for people that depend on me, but I think without an infection of a new virus or several viruses I might live a shorter, but alright life. My chance of suddenly dying because I got light headed in an elevator now being slightly higher than my chance of being crushed by a vending machine.

When reading this sentence:

> We did not observe an increased incidence of neither pericarditis nor myocarditis in adult patients recovering from COVID-19 infection.

you should be careful not to interpret this as evidence of absence. The previous sentence gives confidence intervals:

> Post COVID-19 infection was not associated with either myocarditis (aHR 1.08; 95% CI 0.45 to 2.56) or pericarditis (aHR 0.53; 95% CI 0.25 to 1.13).

Here a 95% CI from 0.45 to 2.56 means that the data is statistically consistent with myocarditis being 0.45 times as likely in people with COVID infection, or 2.56 times more likely.

The sample size here is simply not enough to be more precise, simply because myocarditis and pericarditis are so rare. (It's hard to be precise about the rate of something that happened in only nine COVID patients in the study!) Hence you should not interpret this as demonstrating no difference between people with and without prior COVID infection -- merely bounding the size of the difference that may exist, and saying it can't be more than roughly a factor of 2.5-3.

To be blunt, the authors are wrong to say in their Conclusion that "Our data suggest that there is no increase in the incidence of myocarditis and pericarditis in COVID-19 recovered patients compared to uninfected matched controls." Again, the confidence interval shows that a 2x increased incidence of myocarditis would be consistent with the data.

This is a widespread misinterpretation of statistics and one that has been around for decades, so please excuse me for taking every opportunity to complain. (e.g. https://www.statisticsdonewrong.com/power.html#the-power-of-...)

I had a vertigo issue crop up recently and was able to get it diagnosed (working in military aviation they take this stuff pretty seriously); I don't know that it will help but it's one avenue to look down:

One of my inner ear canal output signals dropped by about 75%. There is a diagnostic test they can do; more basic tests showed nothing but this more sensitive one showed it clear as day. No-one can tall me WHY the nerves are outputting a weaker signal and I couldn't tell you if it's related but it's something that doesn't get checked much.

I had an 8 week dizzy spell in fall of 2020. Never had anything like it before, didn’t have any other symptoms. Went to ENT and ears were completely fine.

I have no idea if it was anxiety or Covid, but the dizziness was disorienting, at the worst I couldn’t walk , it felt like I was on a boat. During this time I had anxiety attacks almost non stop-triggered by the vertigo. As soon as I started to notice the vertigo I would begin to spiral because it was so unprecedented and disorienting. It just cleared up on its own after 8 weeks.

Part of the vertigo was dizzy spells every time I stood up.

I had ~ptsd from it for a full year, every time I stood up I would brace for the vertigo ,

Hope you find some relief soon
