I was stung by either a yellow jacket or Africanized bee this morning - twice on my left labia and twice on my inner thigh. I sought medical attention, received a steroid shot, got prescriptions for antihistamines, pain killers, etc. and am taking them as directed. How long should it take for the swelling to go down? What should I look for? I was stung fifteen times about ten days ago, so I am anxious needless to say.
