Intense radiating pain all the time since getting temporary crown put on, no root canal performed. Is this pain normal?

Severe Pain is never normal.  If your doctor did not tell you to expect it the best course is to call the dentist and get in ASAP.  It is always better to be over-cautious.  My patients have my cel phone number available in case of emergency.

It sounds like you are a seasoned veteran of the dental office. It isn't always a necessity to have a root canal done after a crown is prepared, but if you are in severe discomfort you should call the dentist. Let them do an examination to be sure that a root canal is unnecessary and determine the cause of your pain.
