Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, you are mostly having
bronchitis.
Viral infection is most common cause for this.
And you might be contacted this infection from your daughter or son.
So better to
consult pulmonologist and get done clinical examination of respiratory system, chest
x ray and PFT (Pulmonary Function Test).
Chest x ray is needed to rule out other Pulmonary causes.
PFT is must for the diagnosis of bronchitis. It will also tell you about severity of the disease.
And treatment of bronchitis is based on severity only.
You may need inhaled bronchodilators and inhaled corticosteroid.
You will mostly improve in 1-2 weeks.
Hope I have solved your query.
Wish you good health. Thanks.
