Today is my 15th day being sick. It started with a sore throat and then moved to stuffy nose and cough. Then at the beginning of the week my ears were getting clogged up and impairing my hearing. My whole family had this cold but got over it in 5 days max. Whenever i have any cold it only lasts around 3 days. Now i have a cough, clogged ears, stuffy nose, headaches off and on. What could it be?
