I Get A Very Red Flushed Face When Anxious. It's

I get a very red flushed face when anxious. It's the same feeling I get when I have an alcoholic beverage. I don't drink for that very reason. But now, I am experiencing this flushed, very warm face reaction when stress at work is at its maximum. What to do? Blood pressure is 117/80 so its not that. Diabetes screen normal. I do have high cholesteral (last check 1 mo ago 240). Working on getting this lower by losing weight.
