DDD is just aging of the disks. Based on our own genetics we each progress differently. My 65 year old disks are degenerated like those of the average 80 year old.
You can manage the symptoms/manifestations of DDD by your life style choices and by medical intervention when it is affecting other components of your spine.
Severe DDD, Severe neural foraminal stenosis at 2 levels, moderate canal stenosis at 2 levels, significantly impaired left shoulder & arm function. Chronic moderate compression fracture at C6.
