thanks for asking your question i completely understand your problem if you have shortness of breath while sitting or while walking a small distance , you have to take medications latest treatment recommendations are inhaled drugs like combination of long acting beta 2 agonists and steroids like formoterol and fluticasone plus antichlinergics like tiitropium . these are all inhaled drugs and their benefit is they do not have those threatning side effects like oral drugs and they act directly inthe lung. next and best add on management is pulmonary rehabilitation which improves each and every symptom of copd. pulmonary rehab means exercises that help lung to increase its endurance and decreases breathlessness. by using all these measures surely ur breathless ness will improve thanks/ regards feel free to ask more questions may god bless you with giod health
