Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, this fissing sound is mostly wheezing. Wheezing is whistling sound caused by
bronchospasm and it is more commonly seen in exhalation.
So you are mostly having bronchospasm.
You are also having cold since 2-3 years. So possibility of allergy related disease is more.
Allergy can cause asthma and similar symptoms.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (pulmonary function test).
PFT will not only diagnose asthma but it will also tell you about severity of the disease and treatment is based on severity only.
You will mostly improve with inhaled
bronchodilator (formoterol or salmeterol) and inhaled
corticosteroids (ICS) (budesonide or fluticasone). Oral combination of antihistamine (levocetrizine or
fexofenadine) and anti allergic (montelukast) drug is also beneficial in your case.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
