Hello, on Tuesday and Wed I have appts to activate my Cochlear implant. I am excited, yet in a way concerned that I've built myself up to hear again, but what if something doesn't go right? For those who have had implants before me, what happens on that first and second day when they activate the CI's?. When they get activated, can the volume be controlled like a hearing Aid? If something is unbearable can I just take the over the ear microphone and external magnet off?
