I'm taking hydrocodone and morphine for pain. Im tolerant of the former and the morphine causes a strong histamine reaction. What else can I try?

In brief: Fentanyl

Fentanyl is a potent narcotic which does not produce any histamine release and in patch form less constipation.
But you need to discuss all of your options with your doctor.
