You didn't mention, what antibiotics you were taking. It seems from your problem that your upper respiratory tract infection has converted to lower respiratory tract infection. If the culture report is available, it's better to use antibiotics accordingly. Steam inhalation with salt added to water will definitely soothe you. Lozenges will help you in sore throat. If you tell me the empirical antibiotics which you have already used, I can suggest what next you should take. But best solution will be guided by the culture report. Ideally it should not take more than 96 hrs
