Shortness of Breath
Not being able to get enough air is one of the most frightening sensations we can experience. Shortness of breath is mainly described as an overwhelming tightening in the chest, difficulty in getting enough air and gasping for air. Although this can occur at rest, it is often associated with exertion. Breathlessness that occurs when performing usual daily activities or mild exercise tends to be sign of underlying health problems, usually affecting the heart or the lungs.
