My nostrils have become extremely dry but there is always mucus in my throat. Nostrils are so dry that sometimes I get a weird sensation in my nose. This is happening from past 2 months. And also my face and throat feel warm on touch but whenever I check my temperature its usually 98. I also get extremely anxious about my health. And I need to know is  it something serious or not and what could be the reason behind this ??
