I ' m sick!Now , before you tell me " yes , we always knew that , stupid " , I mean " sick " as in " I ' m ill " ( as you should perhaps have deduced from the title , smartass).I've been sick for the past week or so . Started around last saturday or sunday I think . Certain not - too - pleasant sensations of slightly sore throat and slightly blocked nose which generally feel worse after I ' ve just woken up or eaten a meal or something . Random headaches that occasionally come on , sometimes almost totally ignorable , sometimes quite intolerable .
According to the above context, answer the following question.
What is causing the narrator to feel unwell ?


They have a blocked nose .
