I had it about 4 years ago...absolutely hideous. I coughed so much I couldn't catch my breath between bouts. I totally sympathize with what you're going through.
My physician diagnosed me THROUGH the exam room door . He said he could hear me from down the hall; came in the room with a mask on his face and handed one to me...."You've got pertussis, you are infectious, you are going home and not going anywhere for 48 hours. You are now under quarantine. .
I was feeling pretty good about being immune from the latest round of whooping cough; I guess 4 years is about all I could expect.
