"If I could give Dr Allen a minus review , I would. Because of her not listening when I told her I was having trouble breathing, she missed I had lower lobe pneumonia. ... Because of her incompetence, I have scar tissue now in both lungs and a nodule in one. Other complaints she has dismissed off hand."
