Loss of voice after lung surgery

I had video assisted thoracic surgery for lung cancer surgery on Friday and immediately lost my voice. It is now Monday and no improvement. I can talk in whispers but have no volume and it is quite hoarse. Anybody else have this problem? What treatments are there?
I specifically asked the attending physician of the day but she only said "she was not worried" and offered no information on what to expect or do. I live alone and if I need to talk to someone, they now have trouble hearing me. Automated systems don't hear me.
Anyone out there have similar experience?
