We are truly sorry to hear about the pain you are experiencing, ###, and we are here to pray and offer some biblical encouragement.
Firstly, we want to remind you that God cares about our suffering, as told in 1 Peter 5:7, Cast all your anxieties on him, because he cares for you. WEB
We must also remember that our bodies are temples of the Holy Spirit, and we should take care of them, as told in 1 Corinthians 6:19-20, Or don't you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God's. WEB
While you have not mentioned Jesus Christ in your prayer, it is important to remember that it is through Him that we have access to God. As it says in John 14:6, Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me. WEB.
Let us pray for you:
Dear Heavenly Father,
We come before You today in the name of Jesus Christ, lifting up ### who is in pain. Lord, we ask for Your healing touch upon her. We pray that You will ease her sore throat and back pain and grant her a peaceful night's sleep. We ask that You will help her to recover swiftly and completely from the flu. Please be a source of comfort and strength to her now, in Jesus' name.
We also pray that ### will remember that You are her strength and comforter in times of trouble. Help her to cast her anxieties on You, knowing that You care for her. In Jesus' name, we pray. Amen.
While you wait for God's intervention, we also encourage you to seek medical help if the pain becomes unbearable. God often uses doctors and medicine as means for healing.
