I've been sick for the past 3 days now. The first day it was just a sore throat, which went away by the second day, then that day was non stop runny nose and sneezing, which went away by the third day, and now today I have a headache, sinus congestion, and a 100.4 fever that won't go away even with tylenol, but no more nasal symptoms. No cough yet either. Am I going to die?
