Saturday had fever of 104, painful to move, chills sunday felt better, low grade fever, complained of sore throat has ran low grade fever ever night since saturday, fatigued, seems pale - and looks like he feel awful?

May need throat swab: Sore throat with fever can be strep throat (antibiotics are needed), a cold or influenza (Tamiflu antiviral may be used), or less likely from some other cause such as allergies or irritants. Usually, a person sees the doctor if symptoms are bothersome, recurrent, or don't go away quickly (to see if antibiotics are needed). The doctor can examine, and maybe do a strep swab.
