Dealing with Severe Pain: How Long is Too Long to Wait for Treatment?

going to my doc would require making an appointment. And getting a same day appointment is next to impossible. Cost isn't a concern, as my insurance covers my medical 100%. The pain is from bulging and herniated disks, as well as severe bilateral sacroiliac joint dysfunction. But i also have neck pain from a previous multilevel fusion, as well as chronic bursitis and frozen shoulder on the left side.
