Is this a symptom of anxiety?

[dejablue21]

I sometimes get this really horrible rash that strecthes across my chest up my neck and to one side of my face. It usually occurs when im in some kind of uncomfortable situation, like talking in front of a group of people, or lately when i run into my ex-boyfriend, who i unfortunatly work with. Is anxiety, because once i calm down or remove myself from the sitution it goes away pretty fast. If this is anxiety, would medication help?


Thanks
