Do you feel muscle tightness or heaviness in the chest, throat, or anywhere else in your body? Do you feel anything in your stomach, like butterflies? Do you feel your heart beating faster? Is there a change in your breathing? Is it faster, slower, or shallower? Is it difficult to breathe? Are your facial muscles tense? Is your mouth dry? Do you feel any hotness on the skin? Is your skin flushed, almost as if embarrassed? Are your palms sweaty? Do you feel lightheaded?
