Hi... I am three days post L4/L5 TLIF and I'm having the typical post-surg pain. Yesterday was the worst pain I have ever experienced in my life, as most second days are from what I've read. Here's the thing that has me thinking... In recovery, my surgeon, whom I like very much and came highly recommended, visited me and told me that everything went well. However, the first question he asked me was "Did you have any nightmares during surgery?" I told him no. Later in the day I got to thinking about it. Did I wake during surgery? Was I conscious during surgery and the anesthesiologist didn't catch it? I have no memory of anything like that happening. But did it? Anyone else experience something like this?
