Is the left hand the fretting hand? Please elaborate with more info on braced, such as how and why you think it is a problem.

For me it sounds like you are talking about the first knuckle, so the bass i would assume is in the palm of the hand more and you have your hand turned towards you, hence the reason you ave this feeling? Thats me guessing, as we will all be, so a bit more info or even a photo will always help.
