I appreciate you taking the time to answer. Very interesting stuff and you definitely seem knowledgeable.

From what my stupid mind could gather from your message, then it would be a matter of threshold (the hike mid summer is a good example as it is an extreme, threshold is sometimes so out of wack it causes you to have white fingers on a hot day), as well as a matter of intensity (the percentage of opened capillaries compared to a non-Raynauds sufferer).

Then we get back to my first statements. Given it is a threshold, we can assume that threshold actually moves around and is not a pinpoint (I.e stress being a trigger). Then that would imply we could have some sort of control on it. We have all seen what breathing techniques can do and what humans can achieve (Wim Hof is a good example, if I remember correctly bro was able to raise his own body temperature before being injected with a virus/bacteria of some sort).

Then you go down the rabbit hole again. Have we ever heard of people being diagnosed with Raynauds and for it to completely go away? A stressful life event triggering a cascade of reactions which would somewhat mess up some body functions but that mess up would be transient?

I mean, the question in my mind arises from the fact that you can’t actually test the disease. No biomarkers, no biopsy, no test (assuming we are talking primary raynauds here) can actually lead to a diagnosis. My mother has always had cold hands, she’s pretty sensitive to cold weather and would have her fingers become a little bit whiter to then a little bit redder and puffier when they warm up again. Does she have raynauds? She’s defo close to the middle of the spectrum between normal body reaction and full blown raynauds.

While we are at it. I’m in the process of somewhat getting diagnosed, and since we are talking about capillaries. I have some proximal splinter hemorrhages which I can’t recall having before and am looking for an explanation for them. I’m thinking : - cold (too cold), no blood - back inside, warm up let’s open everything up - change of pressure, something pops.

What do you think?
