Yes. It is better to have an appointment for x-rays, but you don't absolutely need one if someone is available. Another good place in Oceanside is across Vista Way from the end of Rancho del Oro in that medical complex called Imaging Health Services. They have walk-in x-ray and I think they're even open on Sunday - at least they are for appointments because I have one - so you might be able to walk in there even today.
Yes, there is an Urgent Care there with radiology capabilities...
Yes they are in the same building as X-ray. There is a CT and ultrasound as well.
