Nervousness at the sight of a person is commonly associated with social anxiety. Patients with social anxiety are afraid of socializing, especially when interacting and communicating with people, and appear to avoid awkward social behaviors and activities. Patients show severe anxiety reactions when communicating with people and meeting them, as they are at a loss for words and are afraid to look at each other. The patient obviously feels that this reaction is unreasonable, but cannot control it and cannot get rid of it. Patients avoid making a fool of themselves and therefore constantly avoid social situations, which seriously affects their work, study, life, career and social functions. This social anxiety disorder mainly starts in adolescence, mainly due to the fear of being noticed in front of others and the fear of embarrassment, so the patient quickly disengages from specific scenarios and experiences symptoms of plant nerve dysfunction. For patients with social anxiety disorder or social phobia, psychotherapy and medication can be used to get good results.
