My bf had a fight with his friend last Friday evening. I tried to solve their problem but he pushed me. Suddenly a guy hit my bf with a plate to his eardrum. Blood was coming out slowly. Then we took him to the nearby clinic. The doctor told that there is hearing loss for him and suggested wearing hearing aids. I started my research on different hearing aids. I have scheduled an appointment at a nearby clinic which provides the hearing aid services in Toronto. I'm confused with some queries. Is it OK for him to sleep with his hearing aids? How many years should he expect for his hearing aid to last? Kindly share your ideas.
