Sorry to hear about your persistent symptoms. It is one of the unfortunate facts of life that some of these upper respiratory tract infections can persist for some period of time. Often, the worst effects of the illness will resolve, only to leave nagging symptoms that can last for some months. While this often has a simple explanation, there are other times that this can be a sign of something more serious, such as a tumor. For that reason, if your symptoms don't resolve in the expected amount of time, speaking with your doctor
is the right thing to do.
With regards to a sore throat
after a viral upper respiratory tract infection, it is quite common for post nasal drainage to persist for some time. This can result in a drying sensation in the back of the throat that can be quite annoying and can cause the sensation of a sore throat. Coincidentally, acid reflux
can also cause some of those symptoms in some people. Even after the flu has resolved, the nasal drainage can take some time to resolve, which can result in longer lasting, nagging symptoms. Please speak with your doctor about this question and your symptoms.
