Roger:
My sympathies are with you. It is a very unnatural and annoying thing to experience (the tinnitus, that is). For me, it is like a drill and a loud wind combined. It can become so loud that it can actually stop me in my tracks when I'm attempting to do something. It certainly does vary throughout the day. There are aggravating factors such as: loud environmental noise (the food court at the mall is the worst), tiredness/fatigue and caffeine. Oddly, I've found that I do have some small degree of control. That is, I can do things to make the noise less intense. First, if I'm in a loud environment, I simply plug the good ear for 20 seconds or so. That seems to be just about enough time for the tinnitus to peak and begin to fade down. Second, I have tried biofeedback with some success. Interestingly, my mother actually introduced the idea to me and I have to admit, it does help. I simply think repetitive thoughts that focus on decreasing the sound, such as "The right ear noise is getting better, it is slowly going away, it is gone... and repeat for 2 or 3 minutes in your mind. I know it sounds wacky, but in all honesty, it does seem to work. I do not know the specific neurologic pathway between the frontal cortex and the auditory/vestibular system, but there must be some connection.
Also, you should know that it does seem to be slightly better now as compared to last month. It is subtle, but I do think has improved slightly. Either that or I'm just learning to deal with it better! Hope that helps.
Namaste.
