Melanie, I hate fire ants. It definitely sounds like one or more fire ants got you!
The thing with fire ants is they're not just biting, they are stinging. They're like little tiny wingless wasps. It's the venom they inject when they sting that causes the sharp lingering pain and the pustule. Grabbing hold to gain leverage to push in the stinger is the reason they look so hunchbacked when you see them "biting" you.
Did I mention, I hate fire ants?
Amdro is great stuff to have around!
