Was this a flu virus?

Yesterday, around 3:30PM, I started to feel like I do when I’m getting a flu bug. I was a bit achy, tired, a little feverish. As the afternoon and evening progressed, the symptoms got worse. (Fever peaked at 102F and even my hair hurt.) I took ibuprofen around 6:00PM, went to a cooler room in the house from 6:30 to 7:30 and I could feel the fever start to break around 7:30. I sweated for about a half-hour, had a glass of wine at 8:00 and was completely fine by 9:00! There was no intestinal involvement, so I doubt food poisoning. No residual symptoms this morning.

Was it a flu virus? Something else? I couldn’t find anything when I tried Google. I’m grateful for the short duration, but it was strange!

For background, I used to run high fevers at random as a child – 102F to 104F – for no apparent reason. But I don’t remember being achy when that happened. That stopped when I hit about 12 or 13. I remember asking my mom about rheumatic fever, but she claimed that she had me tested. I have no idea if this is true, but I don’t think she would make it up.
