Prayers for Grandma after Minor Stroke

Please pray for my grandma. She has had a minor stroke, but the doctors were able to open the blocked artery. It has been a week and the doctors have just discovered she is bleeding internally at the point they used to access her artery and they had to give her 2 units of blood. The doctors are going to try a clotting agent tomorrow, but if that doesn’t work she will have to have surgery. She is so weak and due to the blood thinners she has been given, surgery is very risky. Please pray for her.
