Can you tell me how one can treat a fire ant sting?

I don't know any firsthand experiences of treating fire ant stings.
It's hard to suggest anything useful about ant stings when there is so much variation in the information you're reading. 
For starters, what species of ant did you experience, and did you get stung more than once? 
I'm going to list some links here that I've found online and follow-up questions that I will ask that I think might help answer your question.
Can you describe the sting to me?

Well, no one was bitten. This is only for future reference.

My first question is to understand if this was a fire ant sting. Do you know what that is? Can you link to a picture or description for me?
assistant
Yes, I know what it is. Do you have any knowledge on how to treat such?

There are a few different approaches to treating the stings of fire ants. 
A topical cream may help. Also, maybe rinsing the area with a few drops of water will help. And you can spread apart any little ants that may still be on the skin. 
Do you remember if it was red or purple or other color? How many stings did you get?

I have some general suggestions about treating an allergic reaction to a sting, but it looks like you might want more specific advice:

If you are looking for a way to specifically treat a fire ant sting, you might want to try using some vinegar to neutralize it.
