Hi Lenny. Welcome to NeuroTalk, a very supportive place.
Now, I've been on I-5 many times in the past but never had an accident on I-5. I keep my accidents here in Iowa.

I'm surprised I've never been diagnosed with TOC after the many accidents I have had but I can certainly relate to the spinal problems.
As forward thinking as Oregon is, I'm surprised you can't find a doc to talk with you about TOC. Is that the case even in Eugene and Portland?
Let us know if you have any problems navigating the forums, and again, welcome.
