Sounds like you really got the short end of the deal. I can't imagine how they got so many things wrong. I had a great trial with my pump, using dilaudid. Morphine was no help. Since I lost about twenty pounds, the pump bulges out a bit from my abdomen, but nothing like you are describing. Now that you are getting some relief from your pump, Please stick with it. How has it impacted your pain level?
I am still having my pump output adjusted, so I am not at a point to say how it is affecting my pain. I wish you well.
