I have terrible tinnitus as well as dizziness and pain associated with a whiplash injury I had in November 2008. It didn't start right away but about 6 or 7 weeks out. Has anyone had something like this?? I can't focus or concentrate for long, I'm spacy and in pain. Pain meds don't work. They want to replace C5-6 disc with an artificial disc. Not sure if this is the answer. I also wake with numb arms, freezing cold hands/arms, lots of other symptoms. Can anyone relate to this at all????
