My best friend just went to a pain management anesthesiologist to have nerves in the right side of his spinal cord burned to give him pain relief from chronic excruciating pain from a catastrophic injury.  The anesthesiologist usedfentanyl and morphine and something called dilaudid (sp?) for pain during the outpatient surgery.  Two hours after the procedure he was in excruciating pain again.  He said the procedure felt like torture.  He got zero sleep that night, was up emailing people about his pain level being astronomical.  What are the drug interaction with those three pain medications, he hasnt been very lucid, doesnt remember repetitive conversations, Im concerned, will he be OK?
