@ablack2008 I’m so sorry to hear this about your mother. It’s definitely a scary situation. As @roch said, we’re unable to diagnose your mother. I think going to a Mayo Clinic is a great idea. There are 3 of them:Rochester,MN; Jacksonville, FL; and Phoenix,AZ. When you apply, in a sense, you're applying to all 3. Follow @roch’s directions to start the process. It also helps if you can get her doctors to call or send copies of her records to Mayo ahead of time. The. Mayo Clinic network is another option.

If your mother get’s an appointment at Mayo Clinic or a network hospital, is there someone who can go with her?
