Emergency cover in Riverside, explained
One practice in Riverside offers emergency services, and one posts 24-hour hours. Phone before you set off in every case. Hospitals divert when their ICU is full, overnight staffing changes, and posted hours are the first thing to go stale in any directory — including this one.
Before you drive: what "emergency", "24-hour" and "out-of-hours" actually mean, the symptom triage list, and what happens when you arrive.
