Do you have any OTC antihistamines in the house? Like Benedryl or Clairitin? You might want to take one.
While ant bites aren't usually a problem, even for someone as highly allergic as me, that many could bother anyone.
You should also take a shower and scrub as much as you can to stop anything from continuing to get into your skin.
Is someone with you? If not, then be watchful of breathing problems. You should call 911 right away. If there is someone else there, then that person can be in charge of deciding when or if to call for help. I've had allergic reactions that affected my breathing. It never got to a dangerous stage but had I been alone, I would have called for help.
