It can start in childhood, resolve, recur or develop in adulthood. Many people have both asthma and allergies. Unlike an allergy, asthma is an inflammatory disease of the lung. Since your nose connects to your lung, the inflammatory process can occur along the entire airway. Once the airway begins to swell, breathing becomes difficult.
Asthmatics are often short of breath and have a feeling of tightness in the chest.
All asthmatics should be under a doctor's care to manage their disease, to keep it under control and to keep them healthy.
