Tinnitus problem (no hearing loss)

I am Archana. I am suffering with tinnitus problem from 1week..with Heee sound . It get worse when I heard normal traffic sounds also. I had consulted ent doctor also. Performed two tests regarding hearing loss and is there any infection related. He said no problem regarding that. You need to take rest. And also he said I may get this because of using headphones and may be because of lack of vitamins. When I am in silent area like home the sound will be reduced. When I read about tinnitus problem in Internet. I heard that tinnitus problem doesn't go away..is it true. I am very much depressed after reading all those in online. Please help me to know in which stage am I..? Is this permanent or temporary.. is there any solution.. or is there any foods get rid this problem..
