Thank you for your question. I am Dr Asanghanwa Carlson. I would say from your description you have got a pneumonia which is a lung infection probably due to a bacteria called Pseudomonas. Other germs could also cause this. However I would say you need to seek urgent medical attention at the ER so appropriate tests are done on your sputum so the germ is identified and an appropriate antibiotic prescribed. This is necessary as you have already taken other medications with little or no relieve. Good luck
