Hello! Looks like you might be having bronchitis with infection .. Do you wheeze ? Is this the first time you are having such symptoms or you have had them anytime earlier too ? Was it exposure to cold or rain that precipitated these symptoms ?Do you smoke ? Kindly consult a physician in person, get yourself examined and get your sputum examined for culture and sensitivity, the test that will tell what organism has caused your Infection and what drug will work for you . for your breathing difficulty you might need bronchilator drugs which will dilate your airways and ease your breathing .you might need a short course of steroid too.Also once your Infection is controlled you can undergo a spirometry testing(pre and post bronchodilator) if thought necessary by your physician
