I have burning lips, too. And my nose, face, basically everywhere at this point. I have small fiber, autoimmune mediated. I think it's just part of the small fiber fun. For me it is, at least. I feel like somedays it is worse than others, but they are burning up a storm right now. I use the sweet mint EOS chapstick and it does have a cooling effect that is a bit short lived, but better than nothing.
