crohns and bone pain

by shell
(australia)

I have had crohn's for many years with one surgery and about a 130 hospital admissions. Now for the past 6 months I have encountered what was mild bone pain and now chronic bone pain particularly in the hips lower back full leg and feet. I have nunbness and burning feelings in different areas with permanent numbness in my feet underneath, with pain being so severe that i can not stand on my feet at times. I take several medications for crohns and work fulltime when i can. Does any one have any suggestions as to what i can do to get rid of this agonising pain?
