OMG..CB...I wish I could show you my CAT scans I had done before surgery. All the air passages/sinuses showed up white! Showed them to the main doc who'd been poking useless allergy pills down my throat all my life and her jaw dropped. All she could say was "This is you?? This is YOU?" I don't know how many time she repeated that before she had to leave the room. I wish I had a picture of that face...
