I believe that you are entitled to your medical records. Under HIPAA, the patient has a right to his or her medical records as long as a proper, HIPAA compliant, medical authorization is provided to the medical provider.
I am not licensed in UT and cannot give you specific legal advice. But in your case, you need to put your health condition first. If there is any question that you may have a life threatening condition go to another doctor and have he or she contact the first with an authorization that you sign to obtain your records. You can pursue legal remedies, if any at a later time. Under the law there is a concept that you must mitigate your damages. And under the facts as you have presented them, common sense supports a mitigation of your damages by putting your health first.
