First post... Long time viewer.

My wife had a lumbar discectomy 2 days ago. She underwent general anesthesia and experienced intractable vomiting in PACU. Nothing helped her nausea expect for a dose of propofol. Today, all of the sudden, she feels foggy in the head, and has periods of dizziness/ lightheadedness. I've read that anesthesia can be stored in fat cells for quite a while. Could this be the culprit? Or should we be thinking more in terms of the spinal manipulation?

Thanks for any advice.
