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.
