My dry cough is almost 2 weeks now and im having a hard time to breath while to try to cough and i take already a over-the-counter meds, but still sick?

Persisting complaint: With persisting medical complaints that last 2 weeks or more - its time to stop trating yourself and benefit from someone trained to figure it out. It would of course be wise to see you primary care physician as soon as possible.

Need diagnosis....: In order to treat your cough, the etiology of the cough needs to be diagnosed first. Bronchospasm may be causing your cough, especially with shortness of breath. Other possibilities include GERD, post-nasal drip, bronchitis or a combination of factors. These all have different treatments so see your doctor ASAP for diagnosis and treatment. Over the counter cough meds are usually not helpful!
