i have been to the Pain Clinic 3 time's thus far, after my struggling walk down and back to the Elevator my Pain has worsened!!, who would i ask for Wheelchair assist so i can get to and from my appointment?

There is a person who should be sitting at the desk as you walk in the doors. Or you could call ahead and ask the provider to make arrangements for them the provide the wheelchair. That's been done before.

There should be a kiosk on the first floor with security and volunteers to help you
