I am a 20 year old and it sounds like i have croup what should i do?

See your MD: Croup is breathing difficulty and a "barking" cough. Croup is due to swelling around the vocal cords. It is common in infants and children. It is a laryngotracheobronchitis. Croup is usually caused by parainfluenza viruses. Other viral infections that can cause croup include rsv, measles, adenovirus, and influenza. It can also be caused by bacteria, acid reflux and allergies. See your pcp.

Adult croup: Most viral croup occurs between 3 months and 6yrs of age. Sometimes childhood croup can occur up to age 12. Adult croup can also occur but usually mild course due to larger airway. Shoud consult physician for treatment. Humidified air is helpful. If airway starts to feel very tight, or you begin to have severe shortness of breath, you need to be seen right away.
