DDD - reading MRI ?

Let me give you a little history. In the past 6 years i have been to the emergency room 5 times on unrelated injuries. Three of those 5 times i was assaulted by more than 4 people each time and all in all the injuries sustained were fractured orbital, broken cheek bone, broken ribs, hands and fingers broken lacerations on my head/face/body and a number of different injuries. The fourth time i went to the hospital i was hit by a car crossing the street and suffered a hip injury, broken ribs once again and nerve damage in my arm( no feeling in the top side of my forearm). The 5th time i was assaulted by a cop and hit in the head with a flashlight and suffered a fractured skull, lacerations on my forehead and 85 stitches across my forehead. In between all of these things i was in 2 car accidents that i should have gone to the hospital but i didnt. One i broke my thumb and it was barley hanging on but i wrapped it up and it healed but hurts all the time since. The second one i suffered a back injury and since my back hurts and im in chronic pain. I Have arthritis in both hands and they hurt all day every day to the point that when i pick something up they really hurt. My body has been through the ringer and back and has taken a sever beating in the past 6 years and all of this and im only 28. Its at the point that my whole body is in so much pain that it hurts most of the time to even get out of bed Confused . Well my question is the last time i went to the emergency room they did a CT and mri. On the page that says Ct cervical spine it says:
mild motion artifact
there is no free air
there is degenerative disease of the bones, including degenerative disc disease.
What does all of that mean?Thanks!
