Can a wrongly performed NUCCA adjustment be corrected for the atlas?

Hello doctor,

What would happen if my atlas was subluxated to the left, but a NUCCA adjustment was performed on my right side instead? Would the atlas then become subluxated to the right, or would it become further jammed to the left? Could an arterial dissection arise? Also, regarding NUCCA, what specific movements or rotations can you get for the atlas? Can you only raise it or lower it? I am in extreme discomfort after multiple atlas adjustments, and it feels as though it is jammed much too far to the left. Each time my chiropractor attempted to adjust me on my left side, the resulting stiffness and restricted motion got worse. My rib juts out on my left side now, and it feels very sore. My atlas was initially mildly subluxated to the right when my chiropractor decided to adjust it on my left side, which then caused the subluxation to switch sides, so I was curious whether adjusting my atlas on the right would cause it to become subluxated on that side again, or make it more ‘level’? My problems started a year or so ago when I went in to see a chiropractor for mild neck stiffness on my right side. It was nothing unbearable, just some mild discomfort. He then proceeded to adjust my atlas on my left side, and it became ‘jammed.’ I went to him again, hoping to fix it, but when he adjusted my left side again, it became even more jammed to the left, and I felt this unbearable tugging sensation throughout my body, and then my left rib started poking out. Currently, I am taking Gabapentin.
