I have an itchy ear, which usually indicates an ear infection coming on, as everyone here at university is also sick. But for the first time, my nasal passages are very dry and it is difficult to breathe because I feel a burning sensation in my nose and on the roof of my mouth. I'm trying to fight this off before it gets worse so I have been using Tylenol Cold & Flu, and I have also popped a couple of amoxicillin to fight off bacteria causing my ear infection. Am I missing something? Does amoxicillin dry up nasal passages?
