So glad you guys made it through! As someone who once made my husband leave the house because his voice made my skin hurt (I had mastitis at the time), I can say that some of us do get really sensitive to sound with pain. And I used to be able to hear the high pitched noise from tvs.
Good for both of you for knowing your rights as patient/advocate and for not being afraid to ask questions. DH is a doctor and in his experience the docs who get put out are usually the ones least confident in their abilities.
Hugs to you both and hopes for a smooth recovery process.
