yeah the nerve damage tinnitus is so annoying at times...it is always there and I too wonder why it changes and is louder than at other times...
like right now it isn't too bad, but it seems to get louder during the day and quieter at night...perhaps adjusting to the time of day...but I do find if I have something on in the background..some kind of music...that I do much better than if I don't listen to something...
I hope you find the things you need to deal with your problem...mine runs in the background all day 24/7...I don't know what they use these days to help with it...but I do notice that putting music on helps tremendously...
