Thanks for your question on Healthcare Magic.
I can understand your concern.
First of all you need to quit smoking as soon as possible. There is no other alternative to this.
So quit smoking first.
Secondly,
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (pulmonary function test).
3. Sleep study.
PFT will tell you about severity of the disease and treatment of asthma is based on severity only.
You may need newer long acting beta 2 agonist (LABA) (formoterol or salmeterol) and inhaled
corticosteroids (ICS) (budesonide or
fluticasone).
If sleep study is positive for
sleep apnea then you will need CPAP (continuous
positive Airway pressure) machine at night.
Avoid stress and tension, be relax and calm.
Don't worry, you will be alright. First diagnose yourself and then start appropriate treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
