[|Human|] My husband just had knee replacement Wed and came home today. He has cold hands and feels cold in his body. What could be causing it. He has been doing so well at the hospital and seems to be ahead of recuperation. I think it may be the shock on his system. What do I know?
[|AI|]  After knee replacement once patient is out from hospital sometimes due to pain at knee and fear of physio exercises and other things also it can happen. I suggest having check on his blood pressure and sugar level, and ask him to stay relax and nothing to worry. Only if there is fever constantly coming and going then you need to check with your or tho doctor because there may be chances of infection. Otherwise, nothing to worry. Also keep doing physiotherapy for further rehabilitation and keep doing exercises suggested by physio on your own also. I have given you here few guidelines, I suggest following it to have good rehabilitation and early recovery. Take care.
