I am 29 years old man suffering since last one year, shortness of breath, when this condition starts my mouth gets dry and nasal congestion occurs and feel like air hunger. And I have to take breath deeply. I am lil bit asthmatic uses inhaler foracort 200 mg two puff twice a day. I feel heart palpations and some chest tightness as well. I have done many test like echocardiogram, thyroid profile test ecg, pft, cbc I can?t do any physical fasting activity because after that I become out of breath. Please suggest some useful treatment to reduce this problem. Thanks.
