I had bad back pain 2 years ago and my MRI showed that my disc wasn't great - not enough water in it - but everything suggested just mild problems and no DDD was mentioned at all. During the next 2 years, my pain got worse, I went to see a Chiropractor who really helped my pain get under control as I have many tight muscles and my psoas was very tight. After seeing her for a while, I was definitely doing much better although still in pain. Then I was attacked by a dog, fell, broke my L1 vertebrae and my pain in my L5/S1 got a lot worse. I got a new MRI which now showed severe DDD with severe endplate erosion and arthritis. It was the pain from this that lead me to go do the fusion instead of just managing the pain with a chiropractor. So, my question is - how much damage of DDD can be caused by a fall or is it just that the damage was there but the fall aggravated it to a much higher level?
