Terrified I've got flu. It started Sunday night with a very sore throat (it's not strep though, got that checked) the sore throat went on for about a day, but felt ok (plus, a few days before the sore throat I kept feeling very tired) I'm very very scared!!! I feel weak, tired, aches legs and arms etc strange feeling in my head. And I'm worried I feel nauseas! PLEASE PLEASE ANSWER!!! REASURANCE NEEDED!!!
