I have now had disabling tinnitus which sychronises with my hearbeat for 2 years. I have had every imaging possible and the many best eyes look at them and they are all reported as normal. I was diagnosed with somatosensory tinnitus. I can alter the volume with my neck muscles at the back of my neck. Anything which moves these muscles changes the volume and pitch. the volume fluctuates throughout the day. i can move it from the left to the right. it is another form of tinnitus. i would like to know whether anyone has had any success with a chiropractor with this form of tinnitus to either cure it or lower the volume please? I have no pain. i am feeling desperate.
