Nausea after SCS Trial Lead Removal

On day 6 of my Medtronic SCS trial, the two leads were removed from my spine, by my pain clinic doctor, in his office, with no fluoroscopy. I remember feeling some mini jolt sensations as the last lead was removed. By the time I walked to my car, I felt some waves of nausea, and went home to sleep for a few hours. Still was nauseous an hour after waking, and would get a slight headache when standing… no headache when lying down. My neck was stiff, too. Went to ER, and they said if not improved by the next day, that CSF leakage was possible. I had a laminectomy 18 months ago, which had a seroma bump over the incision, which as definitely CSF, requiring a dural repair surgery.
So, the nausea after the SCS leads has me a bit concerned, but w curious if anyone else experienced nausea, after SCS surgery?
