Hi Ed,
Welcome!
DDD is a degeneratice Disk Desease. I have it thoughout my Lumbar spine.
In essence your disc' have lost their "moisture content" thereby loosing their "cushioning properties" to the spine that they were designed to do.
If your not already familiar with DDD I strongly urge you to start researching this hideous disease.
It is degenerative in nature and there is no cure - all the more reason you need to be informed of what it entails.
Many people (usualy older) loose their disc integrity and have NO symptoms. Others may exhibit pain usually from progressive DDD that can and usually does lead to spinal instability.
The fact that your MRI showed NO nerve impingement, displacement is AWESOME best news someone with this could hope to hear.
What symptoms are you having and how severe is your pain?
I'm not familiar w/Schmorl's nodes...perhaps you could do a search on the internet ...or I'm sure one of the others here will know.
Stick around your get a wealth of knowledge from these boards.
again a BIG Welcome to you & to SoapLady
