Have you girls ever had a uti?

So I was diagnosed with a uti today but I actually also had a virus.. now, my body is burning up and my face is flushing! I’m on a generic of macrobid called nitrofurantn. I am supposed to take it twice a day. I took my first pill 3 hours ago. I’m laying here in bed and I am so hot and sweaty.... my face is turning kinda red too. Is this normal for a uti/virus or should I be concerned and keep watching to make sure it’s not getting worse? Thank you, opinions are greatly welcomed!
