Onset Develops as a complication after a cold. Can also be triggered by allergies. Symptoms develop within one to three days of exposure to the cold virus. Symptoms begin almost immediately after exposure to allergen(s). If seasonal/intermittent allergies, symptoms occur at the same time every year. If perennial/persistent allergies, symptoms are present year-round.
Typical Duration Can last weeks, months and even years if ignored. Five to seven days. Symptoms last as long as you are exposed to the allergen. If the allergen is present year-round, symptoms may be chronic.
