I Went To Bed Last Tues Eve & When I

I went to bed last Tues eve & when I woke up my left wrist was in a dangled position (no paina0 my Left thumb & Index finger are fine but the other 3 are useless- wearing a hand brace so my hand is in somewhat a natural position. I think I had a shock in my sleep - I'm scheduled for a CT this coming Thursday. Should I be waiting this long for that test?
