I am new to this platform. I have single sided deafness (R). I have been deaf ince I was a child, and went without a hearing assistance device since I was 6 years old. I recieved the cochlear implant last month and it was activated today. I did not hear any sound, but I am getting tones of pulsating in my head. I don't know if this is normal or not and I am scared I won't eventually hear with this device. Is there anyone on here who can tell me if they had a similar experience on activation... are you hearing things now??
