I'm admitted with pancreatitis. I cannot keep meds or anything down. No drug or alcohol use or abuse. Y would dr refuse to use IV pain meds? She's very adament about no IV med use

Patient advocate. If your diagnosis is established, then there should be no reason to leave patients suffer with pain for no other reason. Consider talking to your doctor regarding why and try to explain to them your need for IV pain meds if that's the case. It's hard to judge here if your doctor is doing the right thing without talking to as well. If no resolution is reached, demand speaking with patient advocate.
Details matter. Cause of pancreatitis??? You must be on IV and have a NG tube.!!!??? Demand to be seen by a gastroenterologist immediately.
