Chest tightness. A sense of tightness in the chest is a sign of a severe dust mite allergy. Chest tightness is a problem because it means that the airways and the lungs are swelling and constricted due to irritation from the dust mites. The chest may feel tight even when a person is stationary, and the feeling gets worse when a person is trying to take a deep breath or is engaged in some sort of intense physical activity. This sensation can alternately be described as feeling like there is something pushing on the chest or feeling like there is a band strapped around the chest.
