The weather saved me from the appointment.
I chickened out. It has been snowing all morning and the way to the car is like a ski slope. I just called the doctor's office and rescheduled. I fall on an even floor, just turning around. No way I can get down the steps and negotiate the path to where the car is. So. we'll have to wait for a diagnosis until the weather gets better; or until I fall and the ambulance has to take me away.
Sorry, now I am grumpy and embarrassed.
This is all Lake Effect snow.
