If you are in the USA, there is probably an urgent care facility that you can go to instead of the ER if what you have feels urgent, but not an emergency. Ex: you can't get an appointment with your doc and you need antibiotics. Lots of urgent care places also have an ER attached and you need to be very clear if you are using the urgent care services or the ER because the ER is much more expensive. You will need to check with the front desk person to make sure so you don't get a surprise bill later on.
