I have lumbar PIVD and severe osteoarthritis both knees for very long time. I had taken pain killers for a long time. Now I am concerned about my liver and kidney status after long consumption of pain killers. All the doctors advised to take surgery. I can't take surgery due to my other health issues. Is there any best Orthopedic doctor that can heal my disease and never have to take pain killers or other medicines ever again ?
