Good advice. I was taken to the ER by ambulance for premature atrial contractions which I mistakenly believed were symptoms of a heart attack. The second time, after getting a bill for $2,000, I drove myself. That was a mistake. I had to wait an hour before seeing a nurse. If it's important call an ambulance.
Next time make a dramatic entrance, come in the ER door groaining, clutching your chest and collapse in front of the admission clerk. You will get taken directly back to the ER.
