Do I Need Stitches? How to Tell — and What We Do at Our Pasadena Walk-In Clinic

Clinician cleaning and closing a cut at Advanced Urgent Care of Pasadena

Kitchen knives, broken glass, a fall on the sidewalk — cuts happen fast, and the first question is always the same: is this something I can bandage at home, or does it need stitches? Here is the same guidance we give patients who call our Pasadena clinic.

Signs a cut likely needs professional closure

  • It gapes open. If the edges of the cut pull apart when you gently release pressure, it usually needs stitches, staples, or skin glue to heal well.
  • It is deep. If you can see yellowish fat, muscle, or anything white at the base, come in.
  • Bleeding does not stop. If firm, direct pressure for 10–15 minutes does not control the bleeding, the wound needs attention.
  • It is on the face, a joint, or a hand. These areas scar visibly or move constantly, so proper closure matters more.
  • It was caused by something dirty or rusty — or by an animal or human bite. These carry infection risk and often need cleaning, closure decisions, and a tetanus update.

Timing matters more than most people realize

Most wounds should be closed within about 6–12 hours (up to about 24 hours for some clean facial cuts). After that window, closing a wound can trap bacteria inside, so many wounds instead need to be cleaned and managed open. In plain terms: if you are debating whether it needs stitches, come the same day. We are open Monday–Friday 8 AM–8 PM and weekends 9 AM–5 PM, and we take our last patient 30 minutes prior to close.

What happens at our clinic

At Advanced Urgent Care of Pasadena's minor injury service, wound care is a single visit: the wound is numbed, thoroughly cleaned, and closed with the method that fits it best — sutures, skin adhesive, or adhesive strips. We update your tetanus shot if needed, dress the wound, and give you simple instructions for care at home (our home wound-care guide covers the basics). If there is any chance something is still in the wound — glass is the classic example — we can take X-rays on-site during the same visit.

When a cut is an emergency instead

Call 911 or go to the nearest emergency room for spurting or uncontrollable bleeding, amputations, deep wounds to the neck, chest, or abdomen, or any wound with numbness or inability to move the area. Urgent care is for wounds that are urgent — not life-threatening.
