Mine wasn’t occasionally… Well, it started out that way in about 7th grade. But when I got to high school, my hands were almost always purple and changing colors. But since I’ve been eating for heat, it only happens very occasionally (example: getting something out of the freezer). Where as before, I was having symptoms in 90 degree weather!
I had mild Reynaud’s for awhile. Eating a lot of salt helped, I think, but it’s something that I think it just connected to poor circulation and poor metabolism. Will probably get better as you heal.
