Has anyone had one or know anything about it?I have intermittent extreme hip pain which is caused by the drugs I have been on for my transplant.I have been on them 25 yrs and the doctors say i am the only patient ever to be on them that long with out having a fracture as they are renowned for weakening bones.At my last scan the hip bone did look thin but I didn't really entertain the. talk of hip replacements etc although they are the norm for people in my situation but I can feel that some day this will be a reality for me.How long is the recovery and more importantly do they work?Any info gratefully recieved xxx
