I have often wondered about this myself. They use paralytics in general anesthesia too. My neuro is adamant about spinal pics, any procedures that involve injecting drugs into the spinal canal. I had 3 spinal anesthesias and then 3 nerve root blocks in my life. I also had two general anesthesia, and after the last one, in 2003 was when I woke up to feeling like I had a stroke, and they could not get my pulse or BP to get into the normal range, both were too low. One year later, they diagnosed PN. Also, I had spinal contusion in a car accident 20 some years ago.

I have a suspicion that something has plagued me since childhood, due to sleep disorders and then also restless leg, but, I am sure all the trauma didn't help.

I suppose I should be happy I made it this long, but, the suffering is not easy to bear at times....no matter how good of an attitude one has.
