Pertussis How Long Does It Take For Pertussis To Go Away?

How long does it take for pertussis to go away? - pertussis

I had whooping cough for more than two months. I took medication and got better, but I'm beginning to get up early again to cough. Four of my brothers, but what had happened.
I also have a recurring ear infection, I took pills twice. He seems to have disappeared when the two weeks are long, but it started a few days later. Should I consult a professional about this?
