Had sudden tinnitus start 3 months ago, cause not found. Various different noises in each ear/head. Seems to change volume throughout the day and pitch also fluctuates. I've been told over time you can get used to it and tune it out, how can I do this when it's changing so much all the time? Feeling low and so down that this will be with me for life now. I just can't believe something so random exists!
