Prayers for my brother

Just wanted to ask for prayers for my brother. He is in the hospital with a rather large blood clot in his arm. They do not know what is causing the blood clot and others to show up. He is on 2 different types of blood thinners and his blood is still thick. They are unsure how all of this is happening and until it is under control, he must remain in the hospital. So if you read this blog and get the chance, pray for his recovery!
