Confused and Concerned

had a very traumatic fall back in 2000. I suffered from headaches, dissiness, arm and hand pains. I went through an MRI  3 years later and was told that I had disk desication @ C3-C4, C4-C5 and C6-C7. I had surgery on the C5-C6 on 2003.  I was involved in a small rear ... [More] end accident where I was hit from behind on July 2006. I went through hell and back after that small accident with the same problems after my traumatic fall back in 2000. I tried therapy, chiropractic, injections and even acupuncture but nothing worked. I got an MRI and  on 2006 and was told that I had a mild posteriordisk bulge at the C4-C5. An MRI on 2008 was don and I was told that the MRI showed  a mild diffuse annular bulge of the disk at C2-C3 and a minimal disc bulge at C3-C4 and a mild narrowing of the disk space and a diffuse annular bulge of the disk at C4-C5. I went through surgery on the C4-C5.

My question to you is did the small car rear end cause any of this or was it already there from my previous truamatic injury/fall from 2000.
