Hello!
I read this article on http://www.cbs2.com/health/local story
Loyala Univeristy Medical Center (CHICAGO)has come up with a new treatment for sudden hearing loss. Also, review your daughters past medications, because there are certain medications (especially antibiotics) I know some one who lost complete hearing in left ear aftr taken Armacacin, doctors tried to revise medical records, but they were unaware that after all his previous visits he requested copies of medical records. They had to settle with him a award him for damages.
Another website is www.cureresearch.com
give alot of other info. Well good luck and I hope this helps you out.
