[QUESTION] Is it normal to have wrist pain when playing 3nps?

So I am transitioning from using index-ring-pinky to index-middle-pinky to fret whole tone 3nps scales. With my old index-ring-pinky, I never experienced pain, or not that I remember.

Recently I decided to transition to index-middle-pinky because I see the majority of guitar players playing that way and I read about the various advantages to be able to play like that as well. I am currently on my fourth day of practicing with this fingering and I feel my wrist sore. Is this normal??

Is there a resource I can watch to make sure that my hand and wrist angles are correct? I also make sure that my thumb is positioned directly opposite to the middle finger, and my elbow touches my ribs.
