When to go to urgent care clinic or ER?

I like this answer:

Urgent care clinics help fill a vital gap when you become sick or injured, but your regular doctor is not available and you can’t wait for an appointment.

“If your sudden illness or injury is something you would normally feel comfortable addressing with your primary care doctor, then an urgent care setting is probably more appropriate than the emergency room,” says Dr. Evans.

If a disaster strikes that threatens your life or your limbs, it's time to go to the Emergency Room. Otherwise you can go to your local urgent care clinic.
