Whatever you do, don't shoot in a position where your elbow, or any other part of your body, begins to "really hurt!" When these things start hurting, they have a tendency (which is a word that kind of sounds like tendons, doesn't it?) to hang around a long, long time.
Instead, hold your bow in a natural position, and learn not to torque it by gripping the handle loosely and alligning your string fingers with the cant of your bow.
One possible reason your bow hand is "janking to the left on release," could be that your shoulders are lined up to the left of the target. Terry's clock, some of his discussions about proper allignment have helped me in this regard.
