Yes they gave me IV fluids. And everything normalized after that. I have had episodes at home though.
My husband just told me my ears was fire engine red. This is an issue that started in 2008. Just my left ear would turn red. And one day it just stopped. Well now that's back. He noticed so I went and took my blood pressure. 128/100. So now I know my red ear directly correlates with my blood pressure going up. A doctor once told me yrars ago the red ear thing is called Erythromelalgia. I sometimes got it in my feet too. My neurologist believes I have small fiber neuropathy. She did say my white matter disease os stable so there's some good news:)
