You might have symptoms of social anxiety if you get overly nervous or worried in presence of other people, or in large or public gatherings. Symptoms are things such as fear of being judged, avoiding people and situations, or even blushing when overheated over trivial issues. Other manifestations are sweating, tremor, or the feeling of a racing heart. Some of the most common symptoms are; replaying conversations over and over in your head, being overly concerned with the opinions of other individuals, and experiencing discomfort when making eye contact. If such feelings hinder your ability to be around other people, or causes you distress it might be social anxiety. These are feelings that should be discussed with a mental health professional, for better understanding, control or any possible cure.
