There is no good time to have a cold sore. But why do cold sores always seem to happen at the very worst possible time? Most often, cold sores occur because of physical or mental stress. Anxiety about an upcoming wedding, job interview, or other special event in your life will create stress. This stress will affect your pH balance, your hormones, and your immune system. Quite often illnesses such as cold and flu will also trigger a cold sore.
