Prayer for a Friend

My friend Cyndie has asked us for prayer for her Grampy, Bob.  He is very elderly and is in the hospital with what they think is pneumonia.  He is suffering terribly and the antibiotics are not improving things.  Can you please pray for him that the doctors will be able to find the right course of treatment for him and that if the doctors cannot find the right treatment that his suffering not be prolonged? Thanks ♥
