I was told by an ENT, who spoke at one of my HLAA chapter meeting, that there is only a small window of opportunity to treat sudden hearing loss with steroids. Since many insurances require a referral from a primary care physician before a specialist can be seen, that window has probably already closed. I don't think there is a good understanding of sudden hearing loss yet. On a positive note, I suddenly lost my senses of taste and smell. Steroid treatment did nothing so I was sent for an MRI. Those scans revealed nothing abnormal. It took about 8 months, but my taste and smell did return without any additional treatment.
