What Causes Red Blotches On The Face And Chest?

I ve been having a problem for about 2 years now. My face, ears, chest, and upper arms with get extremely red and splotchy for no reason at all. It has become much more frequent and I don t know what to do to control it. I was doing some research and came across a website where people were posting that they had the same issue but weren t sure what was causing it. One woman said that her doctor said it could be from hypothyroidism. After I ve looking into this more, hypothyroidism doesn t mention anything about your skin becoming red and splotchy, although I do have a great deal of other symptoms. mm
