<s>[INST] My husband has pulmonary fibrosis, has brackets and rod in his back, and has had replaced both knees and shoulders. He is in constant pain. What can be done to relieve this pain? He has been taking oxycodone 10-325 ace, six per day, but that does not stop the pain [/INST] Hello and welcome to ‘Ask A Doctor’ service.  I have reviewed your query and here is my advice. Apply cold pack when it hurts. Don't apply hot packs as they are contraindicated to be used where implants are settled. Put emphasis on positioning while sitting and standing. Right positioning and ergonomics like sitting straight can work wonders. Do isometric exercises of back, hip, knee, it will also relieve the pain and discomfort. Once pain gets subsided then feel free to contact for further exercises regime and that can be discussed later on.Hope I have answered your query. Let me know if I can assist you further.Regards, Dr. Harsh Swarup </s>
