Hi, Yesterday I Started Feeling Unwell. Loss Of Appetite And

Hi, yesterday I started feeling unwell. Loss of appetite and lethargic. By the end of the day I ached all over. Started getting the shakes and was freezing when I wasn't. Shivers all over my body. I have a cough that hurts when I cough. My chest feels heavy and sore, maybe I am starting to get a runny nose but not yet. Headaches are painful too. I have taken my temperature today and is 37.2 which is normal? I have the sweats today with still no appetite and have been sleeping all morning. Kim
