This is a very common question, and a question that every experienced trial attorney should not only be able to answer, but able to remedy.
Many people do not have health insurance.
When involved in an accident, they need medical attention.
There are many medical providers and many different medical specialties in the Phoenix metropolitan area that are willing to see and provide treatment to injured victims, without payment at the time of service, and wait to be paid at the time the case settles.
How does one find these medical providers?
Typically, your experienced personal injury lawyer will be able to advise you and refer you to the appropriate medical care. Ask your lawyer.
If they can't help you with this, perhaps your lawyer does not have the experience needed to serve your needs. Protect yourself, and find the right lawyer for you.
