I just got done being sick from whatever illness. i have a fever, body aches, & a really bad sore throat. &some how an ear infection too. why is this happening?

Many Causes: You likely have a viral illness. Many viruses cause illnesses like yours; the flu is one. Viruses cannot be treated with antibiotics and must run their course. But you can also develop a bacterial infection, which does require antibiotics. Common sites are the throat, ears, and sinuses. You may want to see your doctor if the throat/ear pain continue or if any of your symptoms worsen.
