I think you’d be wise to put your appt off until you’ve had your CT & results are in. Good forward thinking on your part @Leah. It will save you both time & $. It does look like your whole C-1 vertebra is rotated - downward on the right & upward on the left. Several of our members have visited an Atlas Orthogonal Chiropractor (you can search for posts about this), to try to get their C-1 vertebra moved back to a more normal position. There are also YouTube videos that show the process. I’m not sure how good the results have been but I know some cases have seen success in at least partially correcting the position of C-1. It might be something for you to look into.
