I hope you are a bit better now::)
My experience with tinnitus is that it's the best to treat it with acu points.My husband had it for some time, and within 10 days (more or less) it was gone. But, also, try to be patient and grateful, because your body is trying to tell you something.
As someone already mentioned, it could be connected with your kidneys, with exaustion (thyroid) so you should (if you already didn't) go to make some blood lab tests done, and ask them to check your thyroid hormons, then you will see if there are some changes going on, and still you won't be needing to go and see a doctor.
Then, try to relax more, walk , breathe, meditate.
Also, every day you can try to treat some acu points for the tinnitus:
San Jao 3 and 17, Gallbladder 2 and 43, with Kidney 3 and 6 for the chronic type. Scalp or ear points are also useful. (you can find those points on this web site).
You apply preassure (with your fingers)to those points by yourself.
I hope this helps.....
