6 yr old started with cough, now sore throat, runny nose and fever. her eyes started swelling shut. allergy or something else?

Sore throat: See your doctor to rule out a strep throat as your child has fever and a sore throat. It could also be due to a virus but strep must be ruled out.

Sick child: It would be good to have a little more information. I would probably ask if she been given any medication during this illness. How long symptoms have been present? If just a few days most likely a virus is reason for symptoms. If over 10 days or rapid worsening in less time a bacterial infection possible and may need antibiotics. Eye welling could be allergy if medication given. Needs evaluation.

Cough = allergies?: Allergies do not present with a fever. Generally allergy season starts earlier in most areas. Cough, sore throat, fever are generally symptoms of a cold. Eye swelling can be associated with a sinus infection but generally symptoms have to last longer. Make sure she is not having any breathing difficulties. If so, call 911 immediately.

Viral infection: Generally allergy will not cause a fever so probably an upper respiratory infection is the diagnosis. Can be contagious and needs to see a family doctor to make sure the sore throat is not bacterial infection like strep. Eyes can swell with upper respiratory infections. A cold compress over the eyes will provide relief.
