PredniSONE and hip joint

Hi, i was suffering from MCD and put on Prednisone 60 mg per day in May 2007 and after 4 weeks my Doctor asked to take alternate days and then taper by reducing 10 mg per week and it was stopped without much of side effects. But it was the beginning what i feel as in Nov 2007 again i had relapses and this time i was on 80 mg dose which i completed for 4 weeks and when it was on alternate days i started with my right hip pain which i reported to my doctor and was suggested not to go for any pain killer as it is due to Prednisone.
When pain increased i was advised to go for hip MRI and today after MRI the technician informed that my hip joint is damaged......yet i have not got the detailed report of MRI. It all caused by this drug as i have never fallen or got any other impact. Now i am on bed as i can't move and as others i am also getting swelling on face, water retention etc.
