I have been experiencing shortness of breath since past 20 days. Gasping for air every now and then, had a few sleepless nights too. Met different doctors, took different antibiotics in past 10 days. (augmentin and capo dem) but no difference. X rays are clear and so is blood reports, (with just wbc high). Since past one week my chest, left side has also started paining. I've tried all home remedies and taken all prescribed medications yet it's the same. Shortness of breath is constant. Cough is moderate not constant. Please suggest something, it's been 3 weeks and i'm worried now.
