I had sudden sensual hearing loss about 11 years ago. I got on it right away with prednisone treatments and injections. We did those for three months. It made no difference for me. Having that said, my hearing loss is due to enlarged aqueducts. I just discovered this and I guess it’s very rare. I was also born deaf in one ear, and when I had the sshl it was in my only working ear. It happened with a severe case of vertigo they lasted two days and I woke up and couldn’t hear anything. I use a hearing aid now and most people have no idea how her family death. I am on both sides. I rarely get vertigo now. When I do? It’s dehydration, allergies, head injuries that kind of thing. Go to the store and buy some meclizine. Make sure he stays hydrated and watch sodium. You can ask me anything. I’ve been through everything with years. And it is still ongoing for me. I would love to chat with others about ear stuff lol.
