My tinnitus started in October 2013, two days after I was rear-ended on a California freeway. I have high pitched 'squealing' inside my head. 24/7/365 ever since. The severity fluctuates for reasons which I have been unable to figure out. My heart goes out to everyone suffering from this wicked condition. I'm curious if many others are suffering as a result of a whiplash injury? If so, are there specific treatments that have helped you?
