What Sort Of Illness Do I Have?

About four days ago, i got a sore throat. A couple of days later, i then started to get a chesty cough, a runny nose, a headache. Followed by achey msucles and tiredness. And when i wake up after sleeping, im always covered in sweat, literally 'covered'. I cant usually be warm or cold, im either sweating or shivering. Any ideas for what i have? Flu? Swine flu? Thanks :)
