My 41 year old daughter who has always had mild rosacea and for the past six months is now finding her face flushing bright red and burning, despite seeing two dermatologists and family medicine doctors. Her bloodwork is perfect. Is there any serious underlying diseases/tumors etc. that could cause this? It is only face blushing, not a rash. She has not seen an allergist. The only thing that helped was steroid cream, which her dermatologist said she could not use all the time.
