If you’re suddenly sick or injured, your first thought may be to head to the emergency room. But depending on your medical issue, the ER may not be your best choice.

A good rule of thumb: If you fear the situation is life-threatening or severe enough to cause permanent damage, call 911 or go to the emergency room, If not, try to get in with your primary care provider. They generally keep some appointments open in case one of their patients has an unexpected injury or illness.

If you can’t get an appointment with your primary care provider or if it’s after clinic hours, contact Urgent Care.
