Hello,I am new to myMDA. My name is Sue and I am 55 years old. I have polymyositis and was rently diagnosed with avascular necrosis in the both hips. Does anyone have any experience with avascular necrosis? My doctors have advised me to be extremely careful and use wheelchair and keep presure off hips until I see Orthepedic Surgeron in 2 weeks. Any comments would be appreciated.
