If you’ve ever had an asthma attack, you know they can be terrifying experiences. Your chest may tighten, you may struggle to breathe, and you may become anxious and begin to hyperventilate. Even if you don’t have severe asthma that leads to asthma attacks, the symptoms of mild asthma are inconvenient and annoying. With persistent asthma, you may experience occasional shortness of breath, chest tightness, and coughing or wheezing.
