I just had a discogram.
One of the disks was basically trashed, and I knew it from the mri.
But still, the doctor was able to identify that I am a candidate for an idet, which is minimally invasive. Also it seems that I am having more pain from the less damaged disk above it. The really bad one is l5-si, and doesn't really impinge upon many nerves. So the doctor will repair the one disk, and hit the other at the same time anyway. It seems that the heat application from the procedure stimulates collagen growth. So he hopes that perhaps this other disk will regerate some amount of cushioning.
In any case, I would have thought for sure that I was in invasive surgery based soley upon the mri. Instead the discogram proved that I was able to get by with less invasive treatment.
I have to say though that I had sapsms in my lower back for close to a week after the discogram. So stock up on muscle relaxants and pain meds. Not to scare any one.... But I was slightly taken by surprise by this.
Preparation is everything.
