I have had this from time to time. I haven't had it where it's steamed up my glasses as with a hot sweat, but that one or both of my cheeks gos red, but feels very hot and burning.
It can last a good 2-3 hours for me, but sometimes less.
I've never quite got to the bottom of it really. I've had it this last week when the tiny dose of patch I have went awry, but have also found it improved when I worked on things like my iron, vit D and B levels.
Sorry I can't provide more answers, but just wanted you to know you're not going bonkers! Or if you are, there are 2 of us!
