Why Knowing If A Rash Blanches Is Important

Why do we care so much if a rash is blanchable or not? What does it tell you about the etiology of the rash, and which one is more concerning? In this video I will briefly review what causes blanchable vs non-blanchable rashes and some of the more concerning red flag etiologies to look out for!

Thanks for explaining these more subtle concepts! Residency doesn't really teach us these things, they always focus on the big things (afib, HF, PNA etc) but they never go through these kinds of topics that make us more well-rounded overall. Keep em coming! 💯

Hey thanks for putting in the work to explain these concepts. It’s helpful.

I am an intern and every time i mention a rash my attending wants to know if its blanching vs non-blanching. Never understood it that well before watching this. Thanks!

What if the redness very slightly goes away but is mostly unchanged?

[@hibaaqadan3702]

my rash is non blanchable and my dermatologist said its urticaria, it appears mostly when i travel for long hours or if i walk for long distance, recently i feel pain on my leg if the rash comes

[@hibaaqadan3702]

After 2 years i started feeling pain when the rash comes and its mostly on legs
