Dad is going back to the hospital

My dad is going back to the ER this morning. Mom came over this morning and said his weight is up. We were really hoping and praying that the new pill the doctors put him would work.
I don't know if there is any other water medication out there that will work. His kidneys are really taking a hit from ALL the medication that he is on.
Please this morning as mom and dad drive to LA VA Hospital that the doctors working will be able to figure something out for him.
