This has got to be really scary for you and your wife. I know I am supposed to have a link to request an appointment. I am not really good keeping track of links and it sounds as if you are feeling a bit of urgency.
The little blue square in the right hand corner is an instant link.
That being said if I were in your shoes, I would ask my doctor to send a referral. I know that you would get the best information available, if you could get to Mayo.
How is your wife handling this new event? How are you holding up?
