Note: If breathing problems occur suddenly, see a healthcare provider immediately or go to the emergency room. Signs of respiratory distress requiring immediate attention include increased breathing rate, grunting when exhaling, nose flaring, sweating, wheezing, chest retractions (chest appears to sink in with each breath), leaning forward while sitting to help take deeper breaths, or bluish color around the mouth, on the inside of the lips, or on the fingernails.
