So sorry you had such a terrible experience, doctors really should know better, and to think its a teaching hospital that is teaching young residents to disregard their patient's feelings like that... And worse still to be denied a wheelchair simply because you walked 'in'. I don't think I could have stood for it... Though you probably did better than what I would have done, which would have been two steps and on the floor, let them pick me up and put me on a cart, my fat butt would have been excellent weight training for them and believe me I would have made my weight as dead and off balanced as possible.

But please don't let this get you too down, not all doctors are the (insert explicative) that you had the displeasure to meet, and while sad that the hospital you went to is breeding such cretins... But you did nothing wrong. I hope the results come back with an answer your hoping for. Feel better soon
