Hello, back in 2006 I was given rating of 60% for degenerative disc disease of lumbar spine with status post laminectomy and lumbar fusion. I received a letter from the VA stating my diagnosis is changed to IVDS of lumbar spine s/p laminectomy and lumbar fusion with scar and degenerative disc disease. The closest analogous peripheral nerve is the deep peroneal nerve. Remarks for the VA Dr. the effect of the condition on the claimant's daily activity is severe. Question: What does this mean and will my rating go down or will it increase. Thanks, Kevin
