Pain Management Advice?

Current 4th year med student on an audition rotation in EM. Seems like it should be simple but for some reason I'm having issues when it comes to deciding which pain medications to order for my patients. Tylenol/NSAIDs seem like a safe bet and simple choice most of the time, but choosing when to jump to Norco/Morphine/Fentanyl/etc. and which one to choose at the time seems to be tripping me up. For some reason I feel hesitant to as I'm nervous about overmedicating the patient. Does anyone... Pain Management Advice?
