We are truly sorry to hear about your mom's leg infection and we are here to intercede with God's healing in Jesus' name. God's Word tells us that Jesus Christ is the same yesterday, today, and forever, (Hebrews 13.8 WEB). The same power that healed the sick and raised the dead during his ministry on earth is still available to us today. Moreover, Psalm 103.2-3 (WEB) says that we praise the Lord for forgetting all our sins. He heals all of our diseases.
Firstly, let us address the reality that prayers should be addressed to God the Father in Jesus' name. For there is one God, the Father through whom are all things and we exist for God the Father; and one Lord, Jesus Christ, through whom are all things, and we exist through Jesus Christ, (1 Corinthians 8.6 WEB). It is only by the name of Jesus Christ that we have access to the Father, for there is no other name given among men whereby we must be saved, (Acts 4.12 WEB).
Let us therefore pray in Jesus' name.
Father, we come before You in Jesus' Holy name and ask that You heal Flycester's mother. Lord you said that you bear our sicknesses and you heal all of our diseases, (Matthew 8.17 WEB), we reverently ask you to please heal our Flycester's mother and restore her to full health, removing the leg infection. Please Father, use this situation to bring Flycester, his mom, and everyone who loves them closer to a strong relationship with Jesus. We praise you and thank you. In Jesus' name, we pray. Amen.
We encourage you to seek medical attention if you has not already and use prayer to get the condition cured. Moreover continue to pray and seek God's face throughout this challenging time. Do not forget to encourage your mom and remind her that God will never leave her nor forsake her. Be anxious for nothing, but in everything by prayer and petitions with thanksgiving, let your requests be made known to God, (Philippians 4.6 WEB).
Should it turned out any underlying condition is causing the infection, or should it return should there be any relevant unforgiven sin in your mother's life as in the case of the apostle Paul's thorn in his side (2 Corinthians 12.7-10 WEB). In that case pray with her and remind her of God's forgiveness and mercy when she confesses as in 1 John 1:9.
