so i have been coughing continously for the past month. ive already visited my primary physician, but he did not notice anything wrong. ive taken a week of strong anitibiotics. also a xray of my lungs shows nothing wrong. three weeks prior to my cough, i visited cambodia. my family also start to get this cough about three weeks after i came back. my doctor thinks that this might be an allergy and prescribed some clariton. so far a couple days into the meds, i have coughed about 25% less.
anyone know what this could be?
