Ouch! I was attacked by red ants a few days ago

We were out and about on Saturday and I had some red ants climb up onto my left foot and leg and got some bites.  Some on my foot where any kind of shoe rubs against them, and some up my leg.  We counted 17 bites!  And BOY DO THEY HURT!  I don’t think I’ve ever experienced the kind of burning/stinging sensation that they have caused.  It’s really painful.  I’ve been slathering on the calamine lotion which helps until something rubs against the bites, like a shoe or pant leg.  Then it starts up again.

Here’s a picture of a few of them on my leg:
