ER vs urgent care?

Figuring out whether you or a loved one needs emergency care or urgent care may not be easy, especially if symptoms appear serious.

Urgent care centers typically provide treatment for routine sicknesses and injuries, such as flu symptoms and ankle sprains. Most urgent care clinics, however, are not able to treat some of the more serious conditions, such as those listed above — and may not offer necessary imaging and advanced support services a hospital provides.

If you are unsure if you need to go to the ER, review our helpful guide on when to go to an ER or urgent care.


We accept most insurance providers and welcome Kaiser Permanente members.
