That's just what happened to me. I was sick, my Dr. had been sending me all over to find out what my problem(S) were, x-rays, CTScans, 2nd opinions, etc...Then I was driving, sneezed & hit a mailbox, spun twice and was stopped on a small hill against 2 small trees.
I have gone downhill ever since, fast. That accident was in November, 2003, 6 weeks after I took my neck brace off from removing 3-4-5 discs in my neck. Degenerative neck disease.
