Hi! Sorry to hear about your dad, but you have come to the right place for answers and support. While I can't help you in the doctors suggestions area as I am from MA, I can relate to being a caregiver to a parent. It isn't easy, but is very rewarding to be able to give back after all the years they cared for us. Best of luck to you and your dad and please let us know how things go! Hugs!
