Hi all. Quick review. I had surgery for a herniated disk in march2010 and went back to work for the summer only to go out again. The same surgeon ordered an MRI reviewed it 1hr later and said he saw nothing wrong and my injury is different as symptoms of pain are on opposite side. 2 epidural shots later(no help) symtoms change to pain down both legs with numb foot down left. That was before t'giving. As I'm awaiting a selective nerve root block (lumbar) next week I've started to develope headaches that come and go. They started a few days ago. The pain and numbness symptoms vary in intensity where a week can pass with mostly aches(pain scale 3-4). Flare ups intensify in pain and last several days but the new one with developing headaches has me confused. I was under the understanding headaches caused from back ijnuries don't come from the lumbar type injury but from up higher. I have been taking alot of percoset this past month and wonder if that would be the cause. They are not stress headaches as they come up from behind the neck and don't radiate to the forehead. Any one have any experience like this?
