Cold Sore Triggers: While symptoms are not usually present with an initial infection, certain factors may trigger later outbreaks of a cold sore. These can include exposure to sunlight or other uv light, the common cold or flu, hormonal changes, and emotional stress. By being aware of your cold sore triggers and avoiding them as much as possible, you can help prevent outbreaks from occurring.
