Pitch is a bi-product of having a correct span. If the span is pulling it can create undo wear on the finger. Make sure the span is not too long before adjusting. Secondly if it is on the inside of the finger towards the middle then, taking everything else into consideration, the pitch would want to be adjusted towards the middle or right. It also can depend on the middle finger pitch as well as the thumb lateral.
Lateral pitches in fingers are more for comfort than anything else.

angle it towards the issue or blister in this case
