Your face turns flush and your skin starts to itch. Your
heart begins to beat faster. The itching may be felt all
across your face and extend down your arms to your
fingertips.What is going on? If you're like me you forgot what you
learned in school and had to call ask-a-nurse to be
reminded.You may have taken a little too much niacin, or vitamin B-3.
It's ok, you'll be fine, it will probably wear off in about
half an hour.But it can really make you scared if you don't know what is
going on.What.
