spondylolisthesis
"I've had arthritis for over 30 yrs, which has developed into stenosis & sciatica w/spondylolistesis which means I have no fluid in my disc.  Just found our thru on MRI that this is what's pinching on my sciatica nerve, the disc.  Was in so much pain for three weeks I couldn't walk without help.  Now am taking the gabapentin an am glad to finally be sleeping better instead of getting up every hour.  Can't say that it's totally helped.  Started out taking 300 mg 3 times a day.  Just up to 600 mg 3 times a day.  The gabapentin has seemed to improve my mood.  I'm just happy to be sleeping.  Hope to get more relief with the increase in mg's before I have surgery."
