Sir/madam I am 30 year old suffering from chronic cough since last 7 8 years. Every year in winters it starts mostly in the month of august and last till feb. My doctor diagnosed allergy and prescribed formoterol and budesonide inhaler. But from last week I am suffering from cough, increased heart rate while sleeping, breathlessness, fatigue and some times lightheadedness. I am very worried about it please suggest me something. thanks.
