What to say when you feel pain in the body?

I seek refuge in Allah and His power from the evil of what I feel and what I fear.

Allah's Messenger ﷺ said: Put your hand on the part of the body that hurts and say three times: ”بِسْمِ اللّٰهِ“ “With the name of Allah.”

And say seven times: ” اَعُوْذُ بِاللّٰهِ وَقُدْرَتِهٖ مِنْ شَرِّ مَآ اَجِدُ وَاُحَاذِرُ“
