Pain Leaves from Knee Replacement

Last Friday night at out each I met one of my teachers from high school. She just had surgery for knee replacement. She told me she was in a lot of pain and was very stiff. I prayed for her and then told her to start bending her knees, she said they felt like springs got put in her knees and the pain left!  The next school day she told my little sister that there was still no pain!
