Before you go
Most urgent care centers accept walk-ins, and many let you check in online. Bring a photo ID, your insurance card (or ask about self-pay pricing before your visit), and a list of current medications. For chest pain, stroke signs, severe bleeding, or trouble breathing, go to an emergency room instead.
