I've always struggled with blushing easily and intensely. I've hated it!
I do recommend talking with your parents and a doctor about it. I developed rosacea in my 30's, but have been told (by some rosacea experts that send newletters) that the intense blushing is an early warning sign that rosacea will be a part of one's life.
The sooner it's recognized (and treated), the better! Symtoms can and do become permanent as the years pass. So, keep your eyes peeled to prevent the flushing from always staying present.
