If you have been involved in an injury-causing incident and have sustained injuries, you likely need medical care.
How long do you have to treat for injuries before something more needs to be done?
There is no set period of time. Some people need no treatment; some people need weeks or months of treatment; some people need years of treatment and some people will need a lifetime of care for their injuries. Regardless, you are not limited to the amount of time that you can receive treatment following an injury causing an incident.
However, you are limited in the amount of time you have to bring your claim. For most matters under Arizona law, you must present and settle your claim within 2 years of the injury causing event (different for different types of claims—do not rely on this general information for your individual claim).
If your injuries and ongoing medical care prevent you from being ready to present your claim during this period of time, then you must file a lawsuit to protect your right to maintain the claim.
Either way, the amount of time you can obtain and continue to seek medical care is in no way limited in Arizona.
