Hello Habib, Asthma is caused due to broncho-constriction (obstruction of smaller airway passages) which is indicative of Hyper-responsiveness of air passages. Management consists of: 1. Oxygen inhalation, broncho-dilators and corticosteroids - provide symptomatic relief during acute attack by causing broncho-dilation (dilating the smaller airway passages, relieving the obstruction & increasing airflow to lungs) 2. Montelukast preparations- used as a maintenance therapy. 3. Antihistamines can also be used to provide symptomatic relief. 4. Protection from exposure to cold, dust or other allergens. Though prolonged use of steroid injections have its side effects, the risk-benefit ratio should be taken into consideration before administering them. Presence of pain during coughing or deep breathing can be attributed to either fatigue of respiratory muscles due to labored breathing or due to infection. Investigation like X ray of the chest will be helpful in clinching the diagnosis. If symptoms still persist, it will be better to consult a Pulmonologist & get a proper physical examination done. So that appropriate management steps could be taken. Please let me know if you have any further queries.
