Possible to get fever from allergies?

I am a city girl but went out in the country and farm for a day or two. I was fine until later I started sneezing like crazy and had a sore throat. I thought they were allergies. Went to bed and the next morning I was so tired, sore throat, stuffy nose, and had a fever of 100.8 degrees.

Well all these symptoms went to a fever when I left the country and went back home in the city. I broke out a sweat this morning and my temperature is back to 98 degrees and I feel much better but have a stuffy runny nose still.

Allergies or flu?? Flu caused by allergies?? Idk
