Thanks for your question on Health Care Magic.
I can understand your concern.
Nocturnal
cough and
wheezing are commonly seen in
heart failure and asthma (
allergy).
So better to get done ecg and 2d echo to rule out heart failure.
If these two are normal then no need to worry for heart diseases.
Sometimes
allergic asthma can also cause similar symptoms.
So get done clinical examination of respiratory system, PFT (Pulmonary Function Test).
You may need inhaled bronchodilators and inhaled corticosteroid (ICS).
Combination of antihistamine and anti allergic drugs at night time is also beneficial.
So better to first diagnose yourself and then start appropriate treatment.
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
