Prayers Please (Or Uplifting/Positive Thoughts if Praying isn't Your Cup of Tea)

I am asking for prayers for my father. He had surgery yesterday morning and there were a few unexpected complications. He is home now but he had to spend some extra time in the hospital due to the complications. He is still in a lot of pain and is not able to rest comfortably at this point, even with the pain medications.

Please pray for his recovery to be quick and without complication, for the continued knowledge and tact of the Doctors, Nurses, and other medical workers, for my father to not be eager to resume normal activities (I don't want him ripping his stitches/staples), and for his pain to be managed with the medications.

Thank you,
-Kathryn
