Hi BB,
Sorry you are going through this. As if those tests are any fun by themselves...
I agree it is worth calling your doctor, At least start a record of there being a problem. A majority of complaints against anesthesia have to do with issues resulting from positioning. I have read that the majority of those resolve with time, so odds are you're not stuck with this.
Knowing how sensitive our bodies and nerves are, it may not have taken that much to throw you off. I hope you recover soon!
Sending hugs and healing love,
