I Was Told I Have Avascular Necrosis At The Age

i was told i have avascular necrosis at the age of 36. I'm 6.0, 230lb. have had never had any family connections with this disease. After i had my rt hip break off "the ball upper femur" and part of my pelvis replaced, assume the socket I've suffered from severe pain in both feet and hips ?? pain scale 1-10 its 11. i now take gabapenten 800mg 3 a day, 10/325 hydrocodon usually 5 a day and 1 meloxicam 10mg. I've been on this for 5 years and its not getting better. Thank you Dustin
