Hi. Thanks for your question and information. Read and understood that the one sided lung is fully affected by pneumonia. But the fever is nicely subsiding but developed nosebleed. Nosebleed is not at all common in pneumonia. In fact this indicates septicemia, one of the reasons for epistaxis. I would advise the following: Go back to the hospital. Get relevant investigations. Get continued on proper medications and an opinion of an ENT Surgeon to find out the exact reason for epistaxis so that proper treatment can be started.
