Hello, Since the age of 14 I had increasing problems with a hot face. At any time, for no reason anyone can determine, my face will become overly flushed, and burning, and on terrible days will sweat profusely. The heat is centered high on my cheeks, around his nose and sinus areas. It can be caused by certain foods (which change all the time), high or low stress, in or out of public, or warm or cold weather. The only definite time we have found it to be the worst is when I come down with a cold. I no longer go out in public for fear of things flaring up. Can anyone help me with this? Please let me know What can be the cause of a flushed face?
