Reiki and Arthritic Pain

I am a nurse and have many opportunities to use Reiki in my practice. I had a patient who had a cervical fusion due to arthritic changes in her neck. She was complaining of her hands hurting and it wasn't time for pain medication. I held one of her tiny crippled hands between mine. Within a minute she said her hand was warm and so was her other hand and both feet. These had been cold since the surgery and she was told they were always going to be that way. That was early on in the night shift and they were still warm in the morning. Thank you Reiki.
