When to see an orthopedic surgeon

- Swelling, bruising or a joint that feels unstable
- Pain that changes how you move or play
- Pain that returns every time you train
- An injury that isn't improving after a week or two
Get emergency care if
A bone is visibly out of place or pushing through the skin, you can't put weight on a leg, a limb is numb or cold, or you hit your head and have confusion, vomiting or a severe headache.

How Dr. Guier evaluates your sports injury
Dr. Guier asks how the injury happened, what your sport demands, and your goals for returning. He examines the injured area, compares it with the uninjured side, and uses imaging when it will guide treatment.
He'll review any X-rays or MRI with you and explain what they show before discussing options.
Experience from the mountains

He brings that experience to athletes of all levels in San Francisco and Santa Barbara.
