I have had RetroPeritoneal Fibrosis for five years.  I am currently under four specialists...have tried absolutely everything from steroids (several) to exercising with a pro personal trainer, to being on Imuran for one year...nothing works.    The pain is, on same days, literally unbearable.  I am on morphine, fast relief and long-term.  I am on the verge of giving up.  Can you suggest ANYTHING ?  Thank you.

Summarized question: How can acute retroperitoneal fibrosis pain be treated?
